Shein and AliExpress are some gold mines, you just have to find the right size for you (meaning don't order your regular size until you read the measurements they post for the item that interests you, usually they have Asian sizes which are smaller than Western sizes). The great thing is they ship internationally. I've had a lot of luck with them so far but there were ladies who didn't like what they received. Just do a bit of research before ordering, my opinion.
If you live in the US, you can try Dolls Kill or Forever 21, there's also Yandy and Amazon, of course.
I'm also going sometimes to Goodwill and find interesting stuff, I mix and match a lot. I honestly don't care about the source as long as it looks good on me and serves its purpose
