Overall rating: 4.7 / 5 from 24 reviews.
I wore this as my graduation dress and it was perfect! Not see-through at all, high quality and sturdy fabric which felt super sophisticated! I loved the length on me (5'11) and the sleeves weren't tight at all. I went with a medium but I wish I had gotten a small, Im a size 4 27in waist) for reference!
This was the perfect dress for my Senior daughter to wear for Graduation and show off her cowboy boots too! She looked fantastic! Perfect fit! Great customer service!
I wore this dress for my Uni grad and I loved it! I wanted a white dress that wasn't going to be see-though and that was long enough for me (5'11!) I am so happy with the structure and quality of this dress! I ordered a medium, (Size 4/6, 27 waist, 150lbs, 34b) but I probably could have gone with a small if I wanted it to be more form fitting across my chest.
I wore this for my uni grad & it was perfect!!! It’s a quality & slightly thicker material that didn’t wrinkle but was so stretchy & comfy! I appreciate that the white wasn’t see-through at all. I am 5’10, 150lbs, athletic build & usually wear a 4/6 & this is a medium. The small would have probably been a little bit more form-fitting but with the stretch it would work! Really happy with yet another wonderful piece!
