Urban outfitters sundress

Adorable dress, hate to part with it but my bust is busting after baby. Size medium, there is stretchy smocking at the back but if it stretches at the back it does make the buttons pull apart at the front a bit. A stitch could fix the issue but I just never got to it. Straps come undone so can be adjusted. P2P 16” Length from centre of bust 38”
