Such an amazing dress! Classy and elegant for my courthouse wedding day. Go based off the measurements provided. Im typically a 4 but the guide put me right at a 6 and it fits like a glove, a tad snug in the bust (34C cup). Dont need a bra as the corset top and padding is perfect on its own. Even better than the pictures. Im 5ft2 and if hits anout 2-3 inches above my knees.
