Slippergirlwrote a review of Prana Julz Hooded Top - Long-Sleeve - Women's on August 2, 2011
This top is very lightweight...almost a tissue-weight. The white parts in the pattern are somewhat transparent. The fabric is thinner than what I thought it was going to be, but I still like it. The fit is good. I'm 5'6" and 115 lbs and ordered a small. It seems true to size for a fitted top. If you prefer a looser fit, you may want to go up a size.
By the way, I got the Orchid version of the top.
