skin coloured sleeves?
 

Does anyone know if anything like this exists?
Basically like really thin (so it doesnt make you boil) whole arm sleeves that are really subtle and just look like its your skin, but covers up scars and cuts?

I could really use one of these myself.

Hiya yes their are such a thing. generally its called tattoo sleeves so if you just type that into google you should be able to find the link-it'll cover up scars and tattoos.
I've ordered from them before and it did the job

I found this site but it's US based. I can't see whether they ship abroad, assuming you're from the UK?

Hiya those are the ones i ordered from,yes they defo ship to the UK and although it is obviously going to take a bit longer they were actually really fast :-)

thanks!
