I think they are hideous.
I've particularly hate the "tramp stamp" on the lower back that is popular with young girls.
The two most horrid examples I can think of are:
1. A wedding I went to where the bride wore a strapless low cut dress, displaying her tattooed boobs
2. A granny I see at the school gates who has her shoulders, arms & ankles tattooed. She's now very wrinkled.....and so are her tats. What is supposed to be a dolphin on her shoulder now looks like the creature from the black lagoon.
Yuk!
