I wore this Maggie Sottero dress once at my outdoor wedding. It has been dry-cleaned and is in very good condition. It is pure white, strapless, and floor-length.
Here is the description from the Maggie Sottero website:
Striking lace appliqués adorn the bodice of this romantic fit-and-flare, featuring a sweetheart neckline and godets in the airy tulle and English netting skirt. Finished with covered buttons over zipper and inner elastic closure. Detachable cap-sleeves with lace appliqués sold separately.
Note that there are no sleeves on this dress.
