Rubbing vs UV light for all white tat

I'm looking to get my first tattoo, a swan (my spirit guide) and I really want it in all white for various reasons. It seems that all white tattoos are more subject to fading or discoloration from the sun; however, I was wondering if it would fade or discolor more if it were in a place that was rubbed often? I'm thinking of putting it in between my breasts where my bra strap lies. Should I go for a placement with less sun or less rubbing? Thanks, any help/suggestions would be great!

Both are bad for your tattoo...especially white...try to choose an area that avoids both
