Mens fashion tips

I know the obvious sites like peopletree.com and adili.com. Have any hints and tips to extend choice?
To littlerobbergirl- no I don’t necessarily mean “fashion” in that sense. Lol no need to convince me. I patch my clothes up until they fall apart.. But, obviously, people do want to look nice and sometimes we need new clothes. Better to buy ethical. Always do second-hand and clothes-swapping etc but sometimes need/desire something that’s not. Can’t all be perfect, eh!? Thanks for your suggestions.
Also, needs to be BRITISH - UK.. afraid we can’t buy in dollars here.
