I fell in love with this dress at a store in Connecticut, but they didn’t have my size. Week and a Half before my wedding I found it on formaldressshops.com and it arrived in 3 days!

I wore this as the Mother of the Groom to my son's wedding. I received so many complements! It fit perfectly, the lace overlay was beautiful and nothing snagged it, including the chain on my purse. I am 5'4" but can't wear heels.

First let me start off by saying this dress is gorgeous! I saw this dress and knew my daughter had to have it to go with her Under the Sea themed Sweet 16! I could not find it in store and rolled the dice on ordering it online @ Formal Dress Shops.

I love my dress ❤️ . I felt like a princess wearing it. I received so many compliments. The quality of the dress can be felt as soon as you lift it up. It has a nice expensive weight to it vs other thin cheap material out there. But at a great price! The color is beautiful and it’s everything I wanted. Thanks @formaldressshops for making my dream come true!
