I have a few tattoos, and I think I'm going to get another one after the wedding. I like to get them as my life changes.... anyway, I have a VERY strong opinion about tattoos that show. If you got them to put in a discrete location to hid them on purpose, thats one thing. If you have a big honken tattoo on your neck, that people can see everyday - why WOULDN'T you want to show it off in your sexy wedding dress? When I got my most recent tat on my foot, my mom saw it and said "what about if you get married?" The tat is a memorial for my brother, so I just said, "Then good, I want everyone to see it -- it will be like he's walking down the aisle with me!" I purposefully put it in a place people see so when they say "what's that" I can tell them all about him. Seems kind of lame I guess, but it keeps him and his memory in my life forever!
Short point - there's nothing to be ashamed about or "ugly" about your tattoos showing... they make you who you are!!
