[M - 17] Eclectic Fashion Brands/Styling Tips

Recently I’ve gotten into a habit at thrift shops where instead of spending a bunch of money at once on a bunch of random stuff, I try to put together one or two outfits with things I find. Because of that, I’ve sort of fallen into a rabbit hole of eclectic/maximalist fashion but I feel like I could be adding more!

If anybody has this style or has some kind of knowledge about it, tell me—
a. what are some good brands to look out for when I’m doing this?
b. any good tips for layering?
c. What sort of clothing/accesories should I be looking out for? (e.g. costume jewelry, ties, a specific kind of bag, etc.)
