I will never tattoo my hands or breasts, mainly due to the kind of skin in those areas...
the former just does not generally hold up well when you abuse your hands as much as I do at work & with hobbies, and can be hard to heal (especially tattooing..)
the later is just far too thin and sensitive skin for me - I am prone to blowout so I will probably never risk it
Wrists are another I suppose - my skin is just very very thin and there especially , it may look good fresh, but in 5 years I would probably have a mess...

"full sock" tattoos are really gaining in popularity. I dig it. Looks great with shorts/ a classy dress and pumps - big shock of color or intricate greywash piece... I'm a big fan of the color socks though. Nice way for women especially to bust out with a fat piece of art outside of the typicall back placement ,but not get the stigma that get associated with sleeves in the workforce .
