Oh yar! But the thing is in the 70s/80s the US had far better clothes overall than we did so it's better to buy more American influenced 80s style stuff.
Last time I went to a few vintage shops/stalls in London they had loads of 80s stuff, but it was very very rank. Nasty styles, drab colours or tatty fabrics, smelly, looked like it had come out of a dustbin - so I tend to look on ebay for things that are actually nice or buy 80s influenced stuff new.
I think the last thing I got was this mental 80s C&A jumpsuit with a sort of jungle print and giant shoulder pads, but I've also got 80s style stuff from Asos, Boohoo and Modcloth.
It's pretty easy to do tasteful 80s with the right accessories and makeup alone.
And sod vintage 90s. I was a teen in the 90s and everyone dressed the same. My friends and I wore vintage 60s and 70s in the 90s. Anything else is doing it wrong. What have you got to draw from? Nirvana and My So Called Life. You'll just look like an Alexa Chung wannabe or something.
Personally, I rather go for MC Hammer, but he was really mostly rejiggering the 80s. Or 90s Courtney Love would be better than that Chung woman.
Oops, got a bit carried away there.
