Style dilema

My first goal is to make a atrip to GOODWILL I love thrifting but in canada the best i can find is value village which doesnt have much to offer

I want to change m style to that thrifted, vintage grunge style

kinda like JustACurbsideProphet on youtube.

-highwaisted shorts

-oversized sweaters and cardigans
