Okay, I bought this costume after knowing it wasn't the best after reading reviews. I knew there were going to be things I needed to fix, so if you're crafty and good with sewing, it should be no problem. I bought a size large, to accommodate for my larger chest and hips. The legs are WAY too loose, and the torso it way too short. For a simple fix, I took in the legs and made them tighter, which turned out perfectly, but the torso was still uncomfortably short (excuse my bluntness, but you will most likely have an awkward wedgie/camel toe). So, I'm buying a pair of wet look leggings, and I'm going to cut the suit in half like a previous review mentioned to do. Do not buy this if you are 5'5" or over. The belt is also extremely fake looking, so I just replaced the buckle on it and used to cover where the leggings and top meet. Worked out perfectly! As for the mask, I cut off the goggle piece of the mask and covered the forehead piece with a pair of actual goggles. I also bought new gloves, because the ones that come with it are HUGE and look awful.
All in all, you get what you pay for.
