Great staple dress!

I loved this dress! It's so easy to throw on and warm in colder climates. I was able to wear nipple covers and go braless, which I prefer! I've also rented this dress in green. If it's still around next season, I'll probably buy it.

Beautiful Bordeaux color!

Great color I wore it to dinner and a show with my husband. It was warm, but not too warm. Not itchy either. It was a little long on me. I’m 5’4” 112 for reference & wore the XSI with mid booties. I had to wear pasties to keep my girls in check. I would rent again just for the color!

Flattering but stretches down

Equally heavy and loosely stitched. I am sure that last part was by design, and I just mean the holes between stitching patterns are large and you can see your skin through it. Not some much that it is revealing, but I have incredibly pale skin and I kept thinking there were white dots on my arms and thighs. Nope, just my skin. Dress itself is heavy and could be unforgiving on some body types. I added a belt and pulled some of the material up some it didn’t cling as badly. Overall not sure I would rent again, but it was a solid work to dinner dress.

Wanted to love

Love the color and it fit great except the length(me- I am very short so major maxi) and the neck- oddly tight. It was warm, and not itchy but not soft. It was an almost great dress.

Great fit, wore to work

Layered with a white undershirt for work and loved it. I have thick arms so was thrilled that these sleeves didn't cut off my circulation.

Warm and comfortable

This felt great! The material was thick and high quality. I wore it for my kids baptism and it felt conservative enough for that with long sleeves and full coverage. I wore it with black boots

Very thick knit

This dress was warm and thick, I wore it to church on Sunday and to a Friendsgiving/birthday. Really comfortable, be warned that the sleeves are a snug fit. Still loved the dress and the color, will probably rent in the green, too!

Great for cold weather date night

The dress close fitting — but the thick sweater material means it doesn’t feel too skin tight. Perfect for dressing up or down; I wore it on a date night in winter NYC. Lovely color and great condition! And could wear without heels. I also didn’t have the problem with the bra strap showing.

Snug so you will need shape wear. What a beautiful color! There are gaps in between the knots so you will need a slip as well.
