I wish it was as simple as it was on SL, where you bought an avatar mod (which this basically is) and it was pretty much ready to go. Here, I can't just have an item with everything set up nicely as that would involve redistributing the avatar itself.
I did however post a pretty lengthy tutorial in the comment section of this product: https://dein-ra.itch.io/jwmasccaninelatexoutfit which is also a latex outfit, but for a different avatar.
