This red strapless gown does not have any size tag, so I measured it manually for you using the iPhone Measure app.

Approximate measurements (laid flat):

• Bust (pit to pit): 17.5” (about 35” around)

• Waist: 16” (about 32” around)

• Length: about 54” from top of bust to hem

Based on the measurements, I would estimate it to fit around a US Medium to Large (approximately size 8–10), but please check the measurements against a dress you own to be sure, as the exact size cannot be guaranteed.
