Hi there! I wanted some insight on the Scuba Halfzip sizing.

I usually get the XS/S in Scuba stuff but I wanted a more longer length since I’ll be sporting a pregnant belly soon. Wondering if the M/L would be longer in length without look like a giant paper bag? For reference, I have a slim build, 5’2" and the XS/S falls right between my hip and waist.

I won’t be able to go in stores to try it on so I’m hoping everyone here would be able to help me out. Thank you!
