1. Objective
This analysis estimates the FY2024 Cost of Sales as a percentage of revenue (CoS%) for 20 privately-held fashion and lifestyle brands operating flagship stores on Regent Street, London. As these companies do not publish audited financial statements at the granularity of listed peers, a category-based benchmarking methodology was developed, drawing on a proprietary dataset of 68 publicly-listed comparable companies with full FY2024 disclosures.
2. Data Foundation and Comparability
Financial data for all 68 public constituents was drawn from standardised income-statement fields — specifically Revenue from Business Activities and Cost of Revenues. Because a uniform accounting framework is applied across the dataset (harmonising line-item classification across GAAP, IFRS, and local reporting standards), the CoS% ratios derived here are directly comparable across companies regardless of country of incorporation, reporting standard, or fiscal-year convention. This eliminates the principal source of noise in cross-jurisdictional peer benchmarking — namely, that companies define 'cost of sales' differently under different accounting regimes (e.g. the treatment of distribution, depreciation, or occupancy expenses). The normalised presentation extracts a consistent 'cost of revenues' figure that excludes SG&A in all cases. Consequently, the CoS% ratios reported here — whether for a Swedish fast-fashion retailer, an Italian luxury house, or a US athleisure brand — measure the same economic concept.
3. Categorisation Framework
The 68 public companies were classified into 15 business-model categories rather than mapped to standard GICS Industry codes. This distinction is critical: GICS assigns Inditex, Kering, and Ross Stores to overlapping groupings despite fundamentally different economic models. Our categorisation instead reflects the drivers that actually determine cost structure — price positioning, product mix, target customer, and distribution model (direct-to-consumer versus wholesale). The 15 categories are: Luxury Fashion & Leather Goods; Premium Accessible Fashion; Fast Fashion & Vertical Retail; Contemporary Youth Retail; Athleisure & Activewear; Premium Outdoor & Technical Apparel; Footwear Specialists; Denim & Casual Apparel; Bags, Luggage & Accessories; Kids Apparel; Fine Jewellery & Watches; Optical / Eyewear; Beauty Retail; Sporting Goods Multi-brand; and Value / Off-price Retail. The final category is excluded from serving as a peer set for any private brand — the off-price business model (buying overstock at deep discounts and reselling through low-cost stores) produces CoS ratios that are not comparable to full-price brand owners.
4. Peer Selection
For each of the 20 private brands, three to four public peers were selected as the comparator set. Selection followed a strict priority order: (1) shared business-model category; (2) similar price positioning within that category; (3) similar distribution mix (DTC-heavy versus wholesale-heavy); (4) similar product breadth. Where multiple peers met these criteria, we deliberately selected the ones with the tightest structural resemblance to the private brand rather than the largest or most prominent. A worked example illustrates the discipline of the process. For Alo Yoga, Gymshark, and Vuori — three private premium-athleisure brands operating largely direct-to-consumer — the natural GICS peer group would include Nike, Adidas, and Under Armour. However, these public giants derive the majority of their revenue from wholesale channels, which structurally inflates their reported CoS% (because the retailer margin is embedded in the sale price paid by the wholesale partner). Applying their CoS% as a benchmark would systematically overstate the private brands' costs. We therefore restricted the peer set to Lululemon and On Holding — the only two large-cap athleisure companies with DTC-dominant models — producing a materially different (and more accurate) benchmark.
5. Benchmark Statistic
The point estimate for each private brand's CoS% is the median CoS% of its selected peer set. The median is preferred over the mean because CoS distributions within categories are typically skewed by outliers. Within the Luxury Fashion category alone, for example, CoS% ranges from Prada at 20.2% to Burberry at 56.6% — a spread wide enough that the arithmetic mean would be materially distorted by whichever end of the distribution contained more names. The peer set minimum and maximum are also reported to convey the plausible range within which the estimate sits.
6. Confidence Level Assignment
Each estimate is assigned one of three confidence levels, reflecting how well the benchmark truly represents the private brand: • HIGH — assigned where three or more near-identical peers are available, the peer CoS% spread is under 15 percentage points, and the private brand's business model is well-understood and structurally comparable to the peers. Fifteen of the twenty estimates fall in this category, principally in premium accessible fashion and DTC athleisure. • MEDIUM — applies where two to three similar peers exist but with material difference in scale, price positioning, or channel mix. Six estimates fall here, including Marc Jacobs (post-2021 management buyout from LVMH creates a hybrid luxury/premium position), Barbour, and Bimba Y Lola. • LOW — reserved for brands with no clean public analogue. Two brands fall here: Liberty London, whose multi-brand department-store model has an intrinsically different cost structure because it purchases inventory at wholesale prices from third-party brands rather than manufacturing its own; and SKIMS, whose combination of DTC-only distribution, celebrity-founder brand premium, and shapewear specialisation lacks any listed comparator.
7. Sanity Checks
Every estimate was validated against known industry heuristics before being finalised: (1) DTC-heavy brands typically report CoS% 3–8 percentage points below wholesale-heavy peers, reflecting the absence of retailer-margin leakage; (2) vertically-integrated fast fashion (Zara, Uniqlo, LPP) clusters around 45–55%, reflecting the trade-off between scale-driven manufacturing efficiency and low unit prices; (3) ultra-luxury houses (Hermès, Kering, Prada) sit at 20–35%, reflecting pricing power that fully absorbs manufacturing costs. Where a private brand's estimated CoS% would violate one of these anchors, the peer selection was revisited.
8. Limitations
Three limitations should be borne in mind. First, the estimates are inherently indirect: they infer a private brand's likely cost structure from the observed cost structure of listed comparators, and the actual figure may differ from the estimate by ±5 to 10 percentage points even under favourable conditions. Second, small or niche brands (Polène, Marc Jacobs) have no perfect scale-matched peer — reflected in the confidence rating. Third, multi-brand retailers such as Liberty London operate a fundamentally different profit-and-loss architecture from single-brand owners; the peer benchmarking framework can only produce a directional estimate in these cases, not a defensible point estimate.
9. Conclusion
The framework produces peer-anchored CoS% point estimates for all 20 Regent Street private brands, with 15 estimates carrying High confidence, 3 Medium, and 2 Low. The estimated CoS% range across the private-brand universe is 33% (Tory Burch) to 62% (Liberty London), reflecting the wide dispersion of business models represented among Regent Street's private tenants.
