Thoughs on complimenting a girl for having her belly button pierced or when you notice it first time?

so I was thinking about this as I was at a bar last night and ran into this girl I knew she'd be like in her early 20's. she happened to be wearing this top that was somewhat revealing and showed her belly button. I had never seen her belly button before so I didn't know she had it pierced till then. and it did look really good on her as she has a tight and thin body. but I don't feel 100 % sure I should compliment her on that area of her body. its a rather common piercing but some girls are more open about showing it off than others as its somewhat of a sexual area on a girl and a piercing that's often viewed as sexy for a girl to have.
anyways what are your thoughs if I see her again and its visible should I tell her I like it? or that it suits her or just say nothing , she was also showing a lot of cleavage and has great boobs so the belly button was sort of an after though anyways
