I would buy but on sale
I tried on the xs petite, and liked it but didn't love. the arm holes seemed big, you could see my pink bra peeked through on te sides. also, the material is soft but thin (see through, somewhat). the xs petite, just seemed big overall, i would try the xxs petite if it goes on sale and is available. i am 115 lbs, 30dd for reference.
