I have owned 3 catsuits in the past but I must say this is the best I have ever purchased. I bought a large. The sizing is very generous, the material is really lovely and the quality is excellent! I am a bigger girl (size 16-18) so I was worried it might be a bit soo small for me, but in fact the opposite is the case- if anything, it is a little too loose in places, so I should have opted for a medium rather than a large, as I wanted it really skintight. I am still happy with it though, as I am considering coating it in liquid latex as cosplay/clubbing wear. I am 99% certain I might be sending off for a medium size soon as a girl can never have just one catsuit! Thank you, Soho Girl! You rock!
