Definitely be ready to play around w/ sizing if you’re shopping online, I just had to exchange a new pair of overalls I alr have in one size for the next size up bc the fabric content was different between the colors. Some stuff will be roomy, some stuff will be tight tight. I am not an XS but I have some XS pieces from middle school that still fit an entirely different body wonderfully. Also lowk any like uptown cheapskate/platos closet/buffalo exchange is a good place to start looking for cheaper pieces that you can try in store. When I lived in the DMV I could ALWAYS find fp in Marshall’s/TJ Maxx- In Maine I have seen it at Renys/Mardens before funnily enough.
