Hey,
I'm a professional makeup artist and I often cover tattoos for Brides. Honestly, I wouldn't unless for some reason it makes you not feel good.
If you decide to, find someone who airbrushes body makeup (if you can). Ideally, you want alcohol based body makeup as that will not rub off and make a mess. Regular makeup will, no matter what you do to it.... you'll have to be
conscious of there being makeup on your body. In the end, it is really up to you!
HTH!
