The Reformation Twilight Dress is on sale in all colorways during the Reformation semi-annual sale While Reformation generally runs slightly small to size–its standard woven fabric is a breathable but inelastic rayon–in the Twilight you can try your normal size, unless you are especially buxom, as the smocked back allows some flexibility. The Twilight Dress is available in sizes 0-12, and in petite sizes 0P-12P. I am 5’2, with the following bust-waist-hip measurement: 34-24-33, and found the Twilight Dress in size 0 and 0P to be the best fit for me. LTKSaleAlert LTKSeasonal LTKStyleTip
