I will admit that there were some "tankinis" there as well and those do not bother me so much. Tankinis don't seem to carry as much of an adult connotation in my mind. I was tempted to get a tankini just to make bathroom trips easier (on me).
Even my teenager (13yo) has asked for a bikini this year, but she isn't actually due for a new suit yet. Her one-piece from last year should still fit. I like to let my children choose their clothing, but I will not have them out there slutting it up, luring pedophiles' attention.
What sort of swimsuit do your little girls wear?
The topic of characters on clothes is an entirely other possible rant. Another day, perhaps...
