Yeah Volchok I hear you on the customs. I'm in Canada so I love ordering from SSENSE since it's based in Montreal I can avoid having to pay duty fees. I have ordered a few things from Revolve, and sometimes I've had to pay about $10-15 CAD in customs fees but other times nothing at all. I think it depends on the shipping service; When I have things sent Express Mail International I don't seem to get dinged by customs as often.
And Phukette, I agree sometimes you just have to splurge if you find something you really like that fits you well. My guilty pleasure is Common Projects shoes, I know they're a tad overpriced but I just love the fit and quality so I tend to spoil myself and buy a pair anytime I see them for even a remotely discounted price!
