Tattoos and WLS?
A lot depends on where it is, and how elastic your skin is, and how much you lose. I was careful with mine, and didn't get any in places that would stretch during pregnancy. Too many friends had some warped tattoos after giving birth. It really is a wait and see kind of thing. You could PM "Proximity02" who is at goal and had lots of ink before surgery.
You could easily get a cover up, depending on what you have now. If the tats are in places where you expect to lose weight, it's up to the genetic gods (and your age) as too how much your skin--and therefore tats-- will sag. Then address it. You may find you want coverups tats to disguise any warping, but it could also mark the "new you." (Just give me another excuse to get one, right!). If you want more details, my boyfriend does tats and he could discuss with you, but I'm sure he'll say it's probably going to need some sort of touchup/coverup, but you might get lucky. Just PM me with details about current wt and how it's distributed, size and location of tats, your age, and maybe he can make a guess. He may even be able to design a coverup for you to have just in case, if you send pics.
Glad you've come out of the shadows, and into the moonlight. Don;t have to be a lurker any more....

I have a small butterfly on my upper right breast and after losing my 66 lbs (30kg) it still looks exactly the same. I've had it for so long when I was a rebellious kid about 13. I'm 43 now and I have toyed with the idea to go and get it recoloured as it's faded an awful lot. I also had a bluebird on my left hip and when I had my tummy tuck surgery the surgeon said it will cut straight through the middle of the bluebird so we decided then it should get chopped out and tucked in. So I guess I have the "bluebird of happiness" on the inside.
