This is a very nice nightie. The "satin" material is 95% polyester, 5% spandex and feels very soft, silky and comfortable - great for sleeping. My nightie is "green" and seems to be a shade darker than what's shown on the models. Regardless, it is a beautiful shade of green and I love it! After being taken out of the packaging, the nightie retains the fold lines. I have several satin nighties that did this and some that didn't. Retaining the fold lines is not uncommon, so don't be concerned. They will either iron out, or just wear/wash a few times and they will go away. My other nighties have a V-neck, this is my first one with a drape cowl neck. Looks great on the models, didn't work so well with me, so personal preference on the neckline. The nightie comes with a matching string for the waist to help accentuate the figure, see photos of the models with and without the string. I wasn't a fan, I think the string bunched things up a bit and didn't let the nightie drape as it should - again personal preference. The nightie is made by Ekouaer, I have several other items of sleepwear from Ekouaer which I've found the quality to be excellent. The listing mentions wearing this as a casual, semi-formal or formal dress; I think I'm going to limit wearing mine to sleepwear. Overall, this is a very pretty, comfortable and flattering nightie, I like it and it has my recommendation.
