A tattoo can be forever and most likely will be unless you decide to spend lots of $$ and time to get it removed -
so the advice of waiting and making sure this is what you want is great advice!
I have 3 - I got my first one @ 27 - it is a very small heart with a rose just outside my bikini line below my hipbone - - that was 26 years ago and I have always liked it and it still looks great - color and all! - - the only time it is seen in public is in a swimsuit - - - my 2nd one is on my back shoulder blade - - I would have that one removed as I don't like the placement - strapless dresses etc - it is a purple rose and not very well done -
my 3rd one is pictured here and I LOVE it - had it done 3 years ago -- it is on the inside of my lower leg just above the ankle bone and only about 2 inches long - - the scrollwork above and below it was just that - scrollwork that I picked out at the tattoo parlor - - when I look at it sideways it looks like 2 M's - - my DH and I's names both start with M! So it all worked!He thinks I picked it on purpose so I just let him think that - - "Awwwwww honey you put our initials on there!" - - Uh-huh - yeah right - lol
I will be getting a 4th on the top of my foot very soon - it will be my #1 agility dog's ACTUAL pawprint - - as she walks all over me anyway!
Some ppl say it will hurt a lot more in that location due to the lack of muscle - but I have never thought getting a tat was all that painful - - will see how it goes!
You are smart to think about where it will be and the long term - and know FOR ABSOLUTE CERTAIN that this is what you want - - as I said the only one I would NOT have is the one on my back - the others are very subtle, easily covered and if you weren't looking or asking - not know they were there -
I remember when I got my first one my mother's reaction was this: "I have 2 sons in the Navy and my DAUGHTER comes home with a tattoo!!!!!!!!"
Please excuse the 'stubble' - It was only about 4 days old and I wasn't shaving around it yet!
