Gap Cardigan, Very Dark Navy Blue, Knit, V-Neck Button Down, Size S or XS

This ribbed knit Gap V-neck cardigan sweater goes with anything! It is super dark blue, and has no rips, stains, or tears. My daughter wore and washed it several times, and so it does not look brand new. It measures only 15.5" from armpit to armpit, and stretched it fits this 35" or 36" bust just fine (see photo). Because I'm normally a small or medium and this fits me, I listed it as S...but pls notice that the tag says XS. I hope you love this sweater for its versatility...it goes with anything! Please let me know in the comments if you have any questions or would like additional photos. Thanks!
