Reformation - knit dress

Lovely reformation dress! It looks good on tanned skin! New without tags, purchased and mailed from U.S. It looks flattering, but fits a bit tight for me and I can’t return. NO wearing signs and it is in perfect condition! Of note, I am 45kg, everything else fits, just a bit tight on the arm due to my boobs size, so kindly suggest petite girl to get it!
