This dress is super cute. It's true to the image online. The fabric is light and moves well when walking or catching a breeze. The square neckline, full A-Line shape and bold color-blocking make for an eye-catching dress.
I followed the lead of another reviewer and cut the lining out of the skirt. While I didn't notice a difference in the volume, I did notice I was cooler with it removed and that's before I left my very cool apt.
I'm 5'10 / 147lbs and ordered a medium. I found it to be big on me. A small would have been better. I also found that though I loved the color-blocking, the dress read very boxy. To give a lighter, more feminine look, I opened the back of the dress. Where there was a button & elastic loop closer, I opened that and tucked the fabric in on an angle. I then sewed each corner down on the inside (covered by the overlay), which exposed my upper back some.
Regardless of the alterations I decided to make, the dress is still amazing on its own.
