Chicago by the numbers
Chicago's population has held steady since 2020, at 2,731,585 residents (Census estimates).
Cook County has 1,445 clothing stores with paid employees (Census County Business Patterns, 2023). That is 2.8 for every 10,000 residents, above the national figure of 2.4. 57% of them employ fewer than 10 people. The count is down 13% from 1,666 in 2018.
It also has 70 apparel manufacturing establishments with paid employees. That is 0.13 for every 10,000 residents, the same as the national figure of 0.13. 70% of them employ fewer than 10 people. The count is down 10% from 78 in 2018.
Both are broad Census categories: they count every clothing store and apparel factory with a payroll, not independent labels, most of which sell online with no employees.

What Chicago's weather means for clothing brands
For 3 months (December to February) average highs in Chicago stay under 45°F, so heavyweight fleece and beanies should anchor the line, with tees as the warm-season extra. Rain peaks in May at about 4.1 inches, so plan any outdoor shoot or pop-up for a different month. Summers get hot, with about 20 days at 90°F or more, so a real tee drop for May to September earns its place beside the fleece-led line. Snowfall of roughly 39 inches a year gives a winter drop its own backdrop for product shots and keeps beanies selling well past the holidays. Frost arrives on about 106 nights a year, so local customers notice what a heavier, brushed-back fleece adds, and it can justify a higher price than a standard hoodie.

Ordering from Chicago
When should a clothing brand in Chicago drop fleece?
Right before October. There is no shoulder season here: every month is either tee weather, with highs of 70°F or more, or layer weather under 65°F, so fleece demand switches on at once; plan a second release for late winter.
