BCBGMaxazria pink dress size 02.

BCBGMaxazria pink long dress. One shoulder and zips in the back. Size 02. Chest 15.5” Waist 13” Hips 16.5” 100% polyester. Small scratch on zipper. The only issue I have with this dress is there are block type plastic things sewn in the hem. Please see last photo. You can’t see it when wearing it, I just don’t understand what it is.
