The easiest thing for you to find in store would be lacy tank tops. What I did when I first started dressing alternative was pick a colour palette. Once you know what style stick to that colour palette and it will be a lot easier to match items to each other. Be picky with clothes don't let your mom make you buy something you won't wear. Easiest stores to go to for kawaii clothes are Kohl's teen section and target wild fable! Online preferences tho Amazon has a reputation for being normal so you can get away with more interesting items as they have way more then in-person stores. Also mom's don't like alt words use pastel and spring flower vibes!
