This is an all black under body suit made to wear underneath the armor of a storm trooper costume. The armor is not included, this is for the black under suit only. There is a long vertical zipper along the back of this suit. Their is an opening in the face to allow viability and breathing. This is made of 100% lycra which is a stretchy material so this suit will fit a large variety of sizes. If you are 5'3 to 5'9 and weigh between 130 - 150lbs buy the XL. If you are 5'5-6'3 and weigh 150-200lbs buy the XXL. These are "Asian" sizes so that is the reason as to why it appears to be much larger than what you may traditionally wear.
