Still, you could ask employees to specify cut+size instead of just size (inferring cut from their gender). So I'd put down "men's small" or whatever.
I think if you were being obsessively "fair" then yes you would have to do that (personally, I don't really want a leather jacket its not my thing .. but I could choose one for my SO or my sister or my dad or something)
Guys, all went to fittings. Jackets were right size for whoever was wearing. Fat guys did not got thin guy jackets and thin guys did not got maxi-XXL jackets.
Most garment companies have differing 'styles' depending on gender, as they use different 'patterns' (shapes) for cutting the materials.
Thank you for that very informative comment. So that's why those sweaters I bought in the women's section at Uniqlo don't seem to fit me very well!
