I wore this dress to be in my sister’s wedding. It’s 100% silk and fully lined with 100% Acetate. It has a plunging neckline and zips up the back. Side view doesn’t do it justice, but trust me, this dress can accommodate your girls. You don’t have to be a bridesmaid to wear this. I’ve thought of wearing it to a winter party with the fur collar shown, and if you want this dress, I’ll throw that collar in for nothing.
