Be sure to size down on this Marcella Top! I always size down, I am wearing a size xs. It has a built in band to help those with a larger bust size! These pants are not the exact same but similar from Cos. And my ballet flats are Dolce Vita and are true to size! I wear a 6.5 and they fit so comfortably . LTKFindsUnder100 LTKSaleAlert LTKStyleTip
