Ho-lee Cow! I ordered this beauty with limited expirations (I'm 71, just lost 25lbs & now need my shaper, now, for totally different reasons.
If you know, you know!)
This lovely dress just arrived and I slipped it on for Spankx "mapping"!
I just KNEW the risk opting for a body con style, but I was SO tired hiding a plumper figure & needed a brave refresh.
The Mia was a perfect fit. (Now back to a 10, so L) I had to blink - I did NOT believe how good it made me look. Sleek, no special foundations. Seriously. It took me from Biddy to Baddy.
The hubster going to have to up his date game when I wear this great dress. Thanks for making my week!

I didn’t like the fabric and the fit of the dress for me. I also don’t like that I can’t get a refund. Only a store credit or exchange, plus pay the shipping both ways. I wouldn’t have chanced it if I had known that because it just became a lot more expensive.

This dress is so flattering! I love the fit through the waist and hips. I also love the length and I am only 5’2”. I love the extra lining, no need for a slip! The fabric is very soft. This is a dress you can wear all day!

New Year's Eve Wedding
I love this dress! I received many compliments at the wedding, including from my husband...a big deal! I ordered the black size large which was too big. I returned it with no problems and got the medium sized one, which fits perfectly. I wore faux diamond bling and felt so pretty. I sewed closed 6" of the side slits. I am 5'10", usual dress size is 7.

Love this dress!
First, I love the fabric that is used. It flows! It can be washed and doesn't lose its shape or color (black) and I love the silky feeling. I am short (5'1) and wear between a 6 and 8. I wasn't sure if it would be too long. It hits me a little above the ankle. It has 2 side slits that make walking all that much easier. I also love that it is lined, so that I don't have to worry about a slip. I was torn between the small and medium, but am glad I got the medium since it is still form fitting, without being too tight. I feel like it is a bit more forgiving for me. I have worn this alone and with a jacket/ heels or booties. It can be dressed up or down. This is something that I can make work for any occasion. My hubby loves how I look in it and I love that my hubby loves how it looks! So can't go wrong with this one :) Now just neeed it in more colors!! Thank you for another gorgeous piece!!

Amazing quality and very flattering
This dress is my second piece of the Brigitte Brianna collection. I am 5’4” and a size 8 normally. The dress is amazing quality and very flattering. The fabric is soft and the ruching is a fabulous way to camouflage my tummy. I felt confident and beautiful in the dress. My husband told me I looked like a million dollars! Thank you for making SexyModest clothing!
