COS is the H&M Group's Collection of Style fashion label, and Google Shopping interest for that keyword printed 97 the week of September 5 2026. That is up 22.78% from 79 on August 29 and up 120.45% from 44 on August 8, per Trends MCP get_growth on google shopping pulled September 7 2026. The 261-week get_time_series on the same source runs from September 11 2021 (first print 39) through September 5 2026 and peaked at 100 on February 7 2026. Same-week 2025 printed 40. Google Search for cos is 91 on September 5, flat from 91 over 7 days and up 22.97% from 74 over 30 days, a mixed query that fails the 30-day +25% bar and the 1-year +15% bar (+12.35%). Shopping is the source that clears both mover bars and still has a readable cart climb off July.
About cos
COS is Collection of Style, the H&M Group's mid-price minimalist fashion brand, and shoppers type that three-letter string for coats, knits, and trousers rather than the cosine function, which is why this page follows the shopping cart instead of the search index. Wikipedia dates the first store to March 2007 on London's Regent Street, with a catwalk show at the Royal Academy, an online store in 2011, and a first North American store in 2014. The same page, citing the H&M Group 2022 annual report, put the chain at 259 stores in 47 countries as of December 2022. The H&M Group six-month report covering the period to May 31 2026 counted 252 COS stores and 50 online markets, up from 239 stores and 38 online markets on May 31 2025. The dual-meaning search query is real. This page follows the shopping series because that is the wardrobe cart. Vinted tracks the other late-summer clothes climb on this site.
What the time series shows
Google Shopping interest for cos printed 97 the week of September 5 2026, up from 80 on August 29 in the frozen weekly series and from 44 on August 8, a six-week cart rebuild that still sits 3 percent under the February 7 2026 peak of 100. Last eight weekly prints are 38, 28, 28, 44, 58, 75, 80, and 97. Closest 30-day point is 44 on August 8 (+120.45%). Closest 90-day point is 67 on June 6 (+44.78%). Same-week 2025 printed 40, 2024 printed 46, and 2023 printed 45, so this 97 sits well above those Saturdays. Winter 2026 was the other bulge: 86 on January 31, 100 on February 7, then 89 on February 14. Spring held 81 on April 18 and 84 on May 2, then July cut to 35 on July 4 and 28 on July 25. Last year printed 87 on May 24 2025. Week-over-week percent-change sample standard deviation on the last 52 weeks is 31.27%. The chart window starts September 7 2024.
Why the page charts Google Shopping
A clothing brand people buy should be tracked on a shopping source first, and Google Shopping for cos clears the 7-day +20% bar and the 30-day +25% bar while Google Search for the same three letters fails the 30-day window, the 1-year window, and mixes fashion with math homework. Google Search for cos is 91 on September 5, flat from 91 on August 29 and up 22.97% from 74 on August 8. The 30-day print fails +25%. The 1-year print is +12.35% from 81, which fails +15%. Search mixes fashion with math homework. Shopping is the cart. Parent-brand shopping for h&m printed 6 on September 5, up 50.0% over 30 days from 4, a small-index move next to COS going 44 to 97.
Google Shopping is the story source: 80 to 97 in the frozen weekly series over 7 days, 44 to 97 in 30 days, 261 weekly points, week-to-week sample standard deviation 31.27% on the last 52 changes. Same-day get_growth on google shopping, 7-day window, reads 79 to 97 (+22.78%), a 1-point reprint versus the frozen August 29 print of 80.

get_time_series with source google shopping and keyword cos is the call behind the chart. get_growth on the same pair, windows 7D and 30D, is the headline math: 79 to 97 (+22.78%) and 44 to 97 (+120.45%). Mixing the Google Search 91 with the Shopping 97 would invent a story the APIs do not tell.
