Super cute, try on in store
I would suggest trying this on in store. the xs would've worked (that's my normal size), but i ended up preferring the s. it does have low armholes. the s in the yellow was just right for me, but the s in the navy was too low in the armholes and the shirt was cut a little crooked. still, a very cute and classic top that i know i'll get a lot of use out of.
