You can see on the Banana Republic website that this dress has received mixed reviews. Personally, I like it very much. So much actually, that after ordering and receiving my black Gemma (during one of those fantastic 40% off 3 hour flash sales), I promptly ordered it in this bright blue. It looks rather "hydrangea" on the website to me but I'd call it more of a "cobalt" IRL. When my seven-year-old saw me in it yesterday morning she said "Wow, Mom - you're really blue today! You're not usually so blue!" (Blue is her favorite color so I will take that as a compliment.)
The fabric is smooth and a little unforgiving, so you do have to be careful with the undergarments... but it is a lovely weight and I like the feel. It is a true wrap style, so yes, the skirt could fly open in the wind -- so that is one thing to keep in mind. I didn't have a problem though and felt very comfortable in it.
It's been beautifully sunny here lately but the temps are still hovering a tad below 60, so I added a cardigan. I was also doing a bit of walking, so stayed within my ballet-flat-comfort-zone.
