Not a take home for me
I just tried the blue polka dot one on at my local retailer. i'm 5'3ish, 117#, 34d-dd and usually wear a size 4 or xs in most retailer brands. i tried this in size 2 and had a better fit hence the runs large rating. this is a very plunging neckline. not work appropriate and i'm fairly notorious for being out there. the band in the back didn't hit right at my bra in the back so not sure what to tell you there. the shoulder straps are adjustable. there are 2 buttons so you can tighten it up a bit so y
