We have this issue at work. There are several male empolyees that have tats. Only two of the 5 girls have tats. The one has 2 that are visible in shorts/skirts/crop pants. Very cute, flower anklet chain and a rose. I know she has 1 other, but that is in a spot that is covered by her clothing.
Now the other girl, she has several. Some are very nice, but she has 2 that I just don't get and don't want to explain to my kids. She has one on her calf of Mickey Mouse smoking a joint and holding a bottle of whiskey. Her newest one, that she just loves, is on her lower back. It is Tink and Pinocchio in a postion that I REALLY don't want to have my kids or any other kids see and have to explain it to them. She just thinks that it is the neatest. After she got the 2nd one, she started to wear her lowest rise jeans and cropped shirt she could get away with. It took 3 days before the boss/1 of the owners saw it and addressed it with her. When she got the one on her leg 3 years ago, she got short and skirt previleges taken away. Now, she has to make sure that her shirt falls far enough below her pants waistline, so that this one doesn't show when she bends over or stretches.
When she questioned why she had to cover hers, but no one else did, the dress code portion of the employee handbook was whipped out. She tried to use the stance that it wasn't clothing. All 3 owners told her that they could at any point and time change the verbage of the handbook and if she wanted to take that stance, they would have that portion of the handbook rewritten. She pretty much stopped arguing at that point.
