The dress fit well and has some stretch, so was very comfortable to wear. The "jacket" is lightweight, I didn't expect it to provide warmth, but helped to finish the look when I wanted to feel more formal. Once the party started, off it came and the dress was beautiful on it's own.
The only drawback is the glitter. It fits well with the design, but as with glitter...it gets everywhere. I don't think that it's secured poorly...you just can't keep 100% of it in place.
Prior to wearing the dress I did shake it for several minutes outside hoping to eliminate anything that was loose. I did not wash the dress. However I left a light trail through the evening in my seats and a few random pieces even getting on my face.
I felt comfortable and elegant in this dress. I would buy it all over again.
