Seems like it would be great for hot hot days -the material is very light and the back has a large mesh area for ventilation. The design is very cute and seems like it would be flattering except.....
It runs WAY small. I think I would have needed a large or even x-large.
I usually wear a medium in Women's, but this seemed to fit like an extra small. Yikes! It surprised me because I have a medium sized Castelli jacket and it fits well.
