Feels so good. Looks wonderful
I had my eye on this dress in white. I originally bought it in chai during a sale to see if I liked it. When it arrived I immediately bought the white, too
The fit is great, tight but not uncomfortable. The length is great on me which is always hard as I’m short (5’2”). The only issue I have had is the top sits off my shoulders when I sit, slight adjustment is needed. The material is thick and quality.
I had a tight connection between flights in the airport recently and had to grab luggage, pass through security, go up several flights and run down 20 gates- this dress kept up! It stayed in place and did not look rumpled when I finally arrived (just to find the flight was delayed)
As many others have already said- more colors will be entering my closet.

Obsessed with this dress!
I absolutely love this dress! So flattering and comfortable. Win win.
I’m 5’2 and 112lbs. I ordered two sizes (XS and S) and decided to keep the small. I have it navy blue and in white. As other reviewers mentioned, the white is a little see through, but I kept it because I love the white color. I just put on light undies and bunch the dress up a little so it’s not noticeable.
Vitamin A—please make this dress in more colors! I would love a red, pink, or even a turquoise! Also, a petite version would be awesome.
