How to Select a Flagship Store Location: The Data Behind Getting It Right

A flagship store succeeds when footfall volume, visitor demographics, competitive density, and tourism exposure all align with the brand's target customer. Get one of those wrong and the most prestigious address in the city becomes a drain on margin.

Flagships are the most expensive stores a brand will ever open. Per-square-metre costs run two to five times higher than standard retail locations, and the stakes match the price tag. Yet most brands still pick flagship locations based on a mix of gut feeling, broker recommendations, and the prestige of a postcode.

The brands that consistently get it right treat location selection as a data problem. They measure five specific signals before committing to a lease. This article breaks down each signal, illustrated with a real site selection study: Kookaï's new flagship at 37 Carnaby Street, London, analysed using Gini by Mytraffic's Site Selector workflow.

What is a flagship store, and why do brands still open them?

A flagship is a brand's most prominent physical location. It carries the full product range, occupies a high-visibility address, and is designed to communicate brand identity to both existing customers and new audiences. Unlike standard retail units, a flagship's return on investment extends well beyond in-store sales.

ICSC's Halo Effect III study (2023), which analysed $848 billion in credit card transactions across 69 retailers and 2,103 stores, found that opening a physical store lifts online sales in the surrounding trade area by an average of 6.9%. For emerging and direct-to-consumer brands, the effect is even stronger: a 13.9% boost to online sales after opening a new location. Among apparel brands specifically, a new store drives an 11.6% increase in online spend.

These numbers explain why physical retail investment is accelerating, not declining. JLL's 2025 luxury retail report found that 59% of new luxury store openings between July 2024 and July 2025 were street-level locations rather than malls. Newly opened luxury retail square footage jumped 65.1% in the first half of 2025 compared to the same period in 2024.

The pattern is clear. Brands are not retreating from physical retail. They are concentrating investment in fewer, higher-impact locations, and flagships sit at the top of that hierarchy.

What are the five signals that make or break a flagship location?

A flagship location needs to pass five tests before a brand signs a lease. Each one corresponds to a specific data layer that can be measured and benchmarked before any commitment is made.

To show how these signals work in practice, we will use a real study: the evaluation of Kookaï's new flagship at 37 Carnaby Street, London. Kookaï, originally founded in Paris in 1983 and now Australian-owned, is returning to the UK after more than a decade. The brand currently operates 57 stores across Australia, New Zealand, and Europe. Choosing the right re-entry location was not optional. It was the entire strategy.

The analysis was conducted using Gini by Mytraffic's Site Selector workflow, benchmarking the Carnaby Street site against six comparable fashion retailers targeting similar demographics: Brandy Melville, Monki, & Other Stories, Mango, Reiss, and COS.

How important is daily footfall volume and rhythm?

Raw pedestrian count is the first filter, but rhythm matters just as much. A location with 15,000 daily pedestrians concentrated between 8am and 9am (commuter traffic) tells a very different story from one with the same count spread across the afternoon retail window.

The Carnaby Street site recorded 14,740 daily pedestrians, which is 13% above the benchmark average for the comparable fashion retailers analysed. The afternoon peak (12pm to 6pm) captured 39.7% of total daily traffic, placing most footfall squarely within the hours when fashion retail converts browsing into purchases. Weekends showed a 7% uplift over weekdays, indicating leisure-driven shopping behaviour rather than commute pass-through. During major West End events, peak flow reached 43,886 pedestrians.

When evaluating footfall for a flagship, ask three questions. Is the daily volume above your benchmark set? Does the peak align with your trading hours? And does the location generate weekend and event-driven spikes that extend exposure beyond routine weekday patterns?

Does the visitor demographic match the brand's target customer?

High footfall with the wrong demographic profile is a common trap. A location on a busy commuter corridor might deliver volume, but if the pedestrians skew older, lower-income, or predominantly male for a womenswear brand, conversion will disappoint.

The Carnaby Street analysis showed 51% female visitors, 30% aged 25 to 39, and a predominantly middle-to-upper income profile. For Kookaï, a contemporary womenswear brand positioned around femininity, confidence, and independent style, this is close to an exact match with the core customer.

Benchmarking visitor demographics against your own customer data is one of the highest-value steps in site selection. If you already have stores operating well, extract the demographic profile of your best-performing locations and look for overlap with the prospective site. The closer the match, the lower the conversion risk.

Why does tourism exposure matter more for flagships than for other store formats?

Standard retail locations depend on a local catchment area, the residential and working population within a 10 to 15 minute travel radius. Flagships operate differently. Part of their job is to reach people who will never live near the store but who will encounter the brand, remember it, and convert later through other channels or in other markets.

Carnaby Street draws 3.4 million tourists annually. Of those, 465,000 are international visitors, representing 47% of total tourist footfall at the location. For a brand re-entering a market after 12 years of absence, this international exposure functions as a brand awareness campaign that runs 365 days a year.

London itself attracted an estimated 30 million tourists in 2024, according to VisitBritain data, and the West End captures a disproportionate share of that visitor spend. For flagship selection, the total tourist count matters less than the origin mix. What share of those visitors come from markets where the brand already operates or plans to expand? International visitors who encounter a brand in a London flagship and then see it again in Melbourne, Barcelona, or Auckland are worth more than their single-visit spend suggests.

When are nearby competitors a positive signal rather than a threat?

In standard site selection, high competitive density can signal saturation. For flagships, the opposite is often true. Clustering with comparable brands attracts your target customer and signals that the street has the right positioning for your category.

The Kookaï study benchmarked the location against six fashion retailers with overlapping target demographics. The presence of Mango, COS, Reiss, and & Other Stories on or near Carnaby Street confirmed that the street attracts a customer who shops for contemporary, mid-to-premium womenswear. Kookaï is entering a curated competitive set, not fighting for attention in a generalist high street.

William Oliver, Director of Retail & Restaurant Leasing at Shaftesbury Capital (the Carnaby Street landlord), noted that Soho has become "the sought-after launch destination for brands" entering the UK, with Alohas and Edikted both choosing the area as their UK entry point in the past six months.

The practical test: if the competitors near your prospective flagship are brands your customer already shops at, density is working in your favour. If the competitors are unrelated to your category or positioned at a significantly different price point, the co-tenancy signal is weaker.

How does the local catchment area sustain a flagship beyond tourist peaks?

Tourism and event-driven traffic create peaks, but a flagship also needs a baseline. That baseline comes from the local residential population, the surrounding office workforce, and the transport links that make the location easy to reach from neighbouring districts.

Carnaby Street benefits from its position in Soho, a mixed-use area with a dense residential population, a substantial office and creative-industry workforce, and direct access via Oxford Circus and Piccadilly Circus tube stations. This means footfall does not collapse outside of tourist season or between major events.

When assessing catchment, measure the population within a 10-minute and 20-minute walk or transit radius. Look at the income profile, age distribution, and employment density within that zone. A flagship that relies entirely on tourism without a supporting local catchment is exposed to seasonal volatility and external shocks (travel disruptions, currency shifts, economic downturns in key source markets).

How did Kookaï validate its Carnaby Street flagship in under 10 minutes?

The full analysis described above (site evaluation, demographic benchmarking, competitive mapping, tourism assessment, and catchment profiling) was completed in under 10 minutes using Gini by Mytraffic's Site Selector workflow.

Site Selector works by taking a specific address, evaluating it against the key performance indicators that matter for retail site selection, and benchmarking those metrics against a set of comparable locations chosen by the user. The workflow pulls from Mytraffic's proprietary footfall data, covering 10 million locations across nine countries at 10-metre accuracy, and combines it with demographic, competitive, and visitor-origin data to produce a complete location profile.

For Kookaï, the output was a clear, data-backed validation of the Carnaby Street location across every signal that matters for a flagship: footfall above benchmark, demographic alignment with the target customer, strong international tourism exposure, favourable competitive co-tenancy, and a stable local catchment.

The speed matters. Traditional site selection processes take weeks of manual research, broker consultations, and spreadsheet modelling. When a brand is competing for a prime location against other prospective tenants, the ability to evaluate and validate a site in minutes rather than weeks is a real competitive advantage.

Bianca Vagner Cromb, Kookaï's Creative Director, described the Carnaby Street opening as "a major milestone," noting that the location "provides an optimal opportunity to connect with our customer demographic."

Frequently asked questions

How much does a flagship store cost compared to a standard retail location?

Flagship stores typically cost two to five times more per square metre than standard retail units, driven by prime location rents, larger floor plates, and higher fit-out budgets. Carnaby Street retail units of 600 to 1,000 square feet command rents starting around £250,000 per year. The investment is justified by the halo effect on online sales, brand awareness, and international positioning.

What footfall data do you need before opening a flagship?

You need daily pedestrian volume, hourly distribution (to confirm peak trading hours), weekday versus weekend patterns, and event-driven traffic spikes. Comparing these metrics against a benchmark set of similar retailers in comparable locations gives you the context to judge whether the raw numbers translate into relevant traffic for your brand.

How do you measure flagship store ROI beyond in-store sales?

ICSC's Halo Effect III study (2023) showed that opening a store boosts online sales in the surrounding area by 6.9% on average. For apparel brands, the lift is 11.6%. Measuring flagship ROI requires tracking the online sales uplift in the trade area, brand search volume changes, new customer acquisition rates, and press and social media exposure generated by the location.

What is the halo effect of a flagship store on online sales?

The halo effect describes the measurable increase in online sales that follows a physical store opening. ICSC research across $848 billion in transactions found an average 6.9% online sales lift, rising to 13.9% for emerging direct-to-consumer brands. The effect reverses when stores close: apparel brands saw online sales drop by 19.4% after closing a location.

How long does a flagship site selection analysis take with location intelligence tools?

Using Gini by Mytraffic's Site Selector workflow, a complete flagship evaluation (footfall benchmarking, demographic profiling, competitive mapping, tourism assessment, and catchment analysis) can be completed in under 10 minutes. Traditional methods involving manual research, broker consultations, and spreadsheet modelling typically take several weeks.

Why do fashion brands cluster their flagships on the same streets?

Competitive clustering attracts a pre-qualified customer who already shops in your category and price range. When comparable brands share a street, they collectively draw the right demographic, reducing acquisition cost for each individual retailer. Carnaby Street's mix of Mango, COS, Reiss, and & Other Stories created exactly this dynamic for Kookaï's entry.
