How could any one person find a rubber catsuit that fits? It has to fit the waist, the bust, the arms, legs and neck all at once! I know rubber stretches and all, but I presume such an item is custom-made?
We’re moving out of anything I’ve had experience with, but after clicking around a couple of websites you won’t be able to access from where you are it seems as though you can order them in “standard sizes” (non-customized). However, I’m assuming you have to be quite height-weight proportional unless you look into specialty stores. (I’d also assume they run a little on the tight side.)
(For those interested, I googled “rubber fetish catsuit”.)
Maybe someone with more experience with rubber will bounce back in.
Yeah, couldn’t find that outfit, sorry…but there was general clamoring for cheesecake, so I figured I’d provide what I had. 
Yes, you do have to be in a fairly narrow range of being “height/weight proportionate” to have a stock catsuit fit well. There is a bit of wiggle room - it is rubber, so it will stretch! - but you’ll need to be prepared for “it’s a bit snug here, and it’s bit baggy here” unless you’re willing to wait for and pay for made-to-measure.
Oh, you horrible, horrible man.
