Size 4 is slim! I think it’s perfect because it’s small but you can still find some stuff. It does get dicey though once you get into 4 and below. And the pockets still have decent room. I have a size 4 jeans and size 00 jeans from American eagle that are the exact same but the size. My 00 jeans can’t hold my iPhone 8 but the 4 does! Right now, I am a nurse. My XS scrubs are falling off of me. I’m going back to school for system administrator. I find aritiza has some professional looking stuff and they size really small. I just thrift their items because $80 for a tank top is dumb. I’m going to have a bad time with interviews :(
