Strapless Sweetheart Purple Dress

Worn once as bridesmaid dress. 1st picture is slightly darker than actual color. Idk why the color is so different for the other pics. I bought a size 4, and lost weight so it was altered to fit smaller. More of a size 3 or 2. It is a bridesmaid dress from Alfred Angelo (now out of business). There are two stains on the dress, should come out with dry cleaning. Just haven't had a chance to do it. See 3rd pic just to let of seam & the 2nd pic a small white dot just down & to the left of center.
