I pretty much always wear baggy clothes. Right now I’m gaining weight bc caloric surplus/trying to gain muscle but at my smallest I would fit into XS at some places. Petite sizes can be smaller tho so petite xs can be pretty small but it depends on the brand too. Recently I fit like a 2P dress or something and that worried me, for when I lose weight lol. I subjectively feel pretty average for my height. I have always carried more fat than muscle bu default and I don’t have a tiny, but sort of smallish frame.

Buuuut once in a while you do find clothing that fits you really comfortably and is figure hugging in a flattering way. I think it’s a combo of elasticity within the garment, combined with ruching and also get something an inch or so larger than your actual measurements (for the comfort). It’s rare to find one but it’s possible.
