This is a BoO Small, does it look like I could go for an XS?
You might be able to get away with an xs depending on the shirt since some fit different. I think it looks fine in the two pics though and probably wouldn't return that and order one. If you're at a store that carries them, you might want to try an xs on just for future reference. Plus, the S looks better with more casual summer stuff. I'd prefer it if the pant rolls were a bit lower but everything seems solid
