I wore this dress once as a bridesmaid. It is a stunning dress and in great condition. I ordered it in a size 4 but had to take it in on the sides slightly because I thought I was going to be wearing it strapless. This said, it is probably closer to a size 3 than a true size 4 in the bust area. The length was never altered! I have included details from the designer's website below.

The Wren Dress features a shirred strapless bodice with a sweetheart neckline for a universally flattering look. The A-line skirt features convertible panels that can be raised and manipulated to create alternate necklines and skirt details. A detachable tulle sash that can be used to tie around the waist to create definition and finish the look is included. The dress is fully lined, with a center back zipper.
