The manufacturer of this item is “Leg Avenue”. Material is Nylon and Spandex what makes this dress pretty stretchable. The shoulder straps are stretchy as well. I would say the material feels thin to me. The dress comes in Small, Medium and Large sizes and in one color combination only (red with black stars). Package: the dress was folded in a simple and clear plastic bag. the dress has a pretty good quality. There was no frayed edges or any other defects on it. All sequins were where they supposed to be. But I am not sure yet if they will not fall away from the dress in a while. This dress does not have a zipper.

You can wear tan color bra without straps under this dress. But it’s going to be visible anyway. So I would not recommend any bra at all. You can fix the length of strap. When you are trying to sit down the dress goes up and you have to watch it so nobody would see your panties. this dress shows off a lot of skin. I was feeling very comfortable in this nice dress. It is very tight fitting. Walking around this dress stayed down. It goes less than half the way down to my knees so it is very short.

This dress will not need any ironing. Do not put this dress in the dryer. Let it air dry because you do not want to ruin the sequins. This dress is definitely travel friendly because it is so small and can easily be folded to fit almost anywhere. Plus You don't have to worry about it wrinkling when you put it in your bag.
Overall this gorgeous dress definitely has a glam feeling to it. I would say it's good enough for Oscar ceremony. I loved the dress and absolutely recommend it!
