This dress is almost a perfect summer dress---roomy, comfy, lightweight, pretty, etc. If it were perfect for me, it would be made of 100% cotton, but the polyester cotton used in this dress doesn't feel bad. It's soft, not see-thru, and doesn't seem to wrinkle, which I know I couldn't say about 100% cotton. Arms aren’t too tight but not so big that others can see into your bra. This could be worn loose or dressed up with a belt. If you want a casual, comfy summer dress, this is it.
