For those of you who are new to wearing catsuits, like me, the best thing I can suggest is to double-check your measurements before deciding on a specific size. Also, be prepared for some (understandable) difficulty getting in and out of it. Even with its intended tightness, there were moments where I thought I was going to tear the XXL suit apart, but I did manage to put it on.
Like the similar spandex suit, I think this could do with allowing for custom size specifications, so that wearers can get things exactly right. Shipping wise, it -did- manage to get here (China to the UK) inside the timeframe they specified for the least expensive shipping; taking a total of 24 business days (out of 30) from ordering to delivery (on a Saturday), so I can't really fault them there. And it's a PVC catsuit as well. Not much bad there, either. ;)
