Any recommendations?

hello everyone!

I’m a Portuguese girl with a very typical Portuguese/spanish style, that I have recently found out is boho chic. To me Zara is the perfect store in terms of style. In recent years as I have become more aware I have switched to strictly buying on vinted, but I find myself still only buying from Zara or similar brands on there and sometimes things that are still in store, which is shocking. my point is that I feel like I haven’t really made any changes, instead of buying it on the store im just buying it from someone who just bought it at the store. The problem is I can’t find sustainable brands that fit my style. Buying second hand in person is not possible for me in the city I live in. Basically I’m asking for brand recommendations or just recommendations in general. Thank you.
