Lately, I've found it difficult to find any clothing I like. I don't want to follow trends, so even the ruffles and flower print has been popular lately, it doesn't really appeal to me.

I love blouses like this:

But I can't seem to find them anywhere. Any recommendations for places to buy clothes like this? I've tried shopping vintage, but I have trouble finding my size (5'0, 40 kg). I'm also 21, and don't want to look like a teenager.
