I purchased this dress to wear to an outdoor baby shower August. The material is thin enough that it should not be too hot! The dress is comfortable. It's cute on its own, but would also look good with a kimono or light sweater added (depending on the season/location). The color was a little more blue than I had anticipated (I thought it would be a more gender-neutral aqua color). However, out of the colors offered in my size, I like this color the best for summer (and I don't want an actual blue or pink).I ordered both the medium and large (I'm currently 32 weeks pregnant, 5'5", 155 lbs). The medium fit comfortably, but the material is pretty tight so I felt like it was a little less flattering around my underwear. The large fits comfortably as well, and is a little more flattering. I do like the length of the medium better though. I will probably need to wear a slip under the dress for better coverage. I like how the straps are thick enough that I can wear a bra and not worry about the straps showing.* The first 2 pictures are size medium, and the 2nd 2 pictures are size large.EDIT: When wearing this dress outside in the summer, I really sweated in the areas under my belly and around my hips when I sat. The sweat marks showed.
