This dress is so pretty! The olive green color looks much better in person than in the online photos or the phone pictures I could take. It's less neon than displayed in the add, yet very glamorous. The dress is doubled throughout, and the material is breathable and feels great against your skin. It's perfect for summer vacations. You can see the texture in my close up pic. In terms of fit, I think it's spot on. I am 5'5, 130 lbs and got an S. I could easily close the zipper, with a bit of room left. I chose to wear the dress in a more conservative way cleavage-wise, so if you plan to wear it lower, you probably will have even more extra room. It doesn't feel like too much though, so I would not size down. The fabric has no stretch. Overall, a cute dress in a gorgeous color and really nice fabric. I do recommend it.
