Hi. I am trying to decide between the XS and the XXS. I am around 5'3 and a little over 100 pounds. A small 34B. I want to wear it with sweatpants so I don't need to too long or oversized and the size small looks huge on the models. Cannot decide between an XS and an XXS? For reference I just got the 1/4 zip is an XS and pretty roomy. Would love your thoughts!
