A catsuit is certainly something new and exciting and not your normal bedroom lingerie! If Im honest I would be a bit shocked if my other half presented me with a catsuit on valentines day. I would probably prefer something a little more "traditional" :)
Dont get me wrong, I love to dress up but I would see a catsuit as a little OTT, but thats just me personally! If your OH is really into dressing up and you know she would enjoy it, go for it! It would really make it a night to remember!
