Would never get one myself.
Wife has a couple, some now look bloody awful (Tweetie pie on your butt?) which TBF she agrees with, but the butterfly one on her leg is very nice and very meaningful to her so I can live with that.
I think it's very much a personal choice, but if you get a very prominent one don't be upset if it costs you a job/promotion/shag or whatever, twas your decision.
