Okay, so I had a female toddler and I had finally made a birthday cake. I made her have her birthday and when she turned to a preteen, she was wearing the swimsuit looking underwear and barefoot! I have no idea how I did this but I find it kind of hilarious.
She was wearing a sailor hat and that one dress that matches the sailor hat that is blue. (Please excuse my lack of decent descriptions.)
Anyways, if this can be proved to cause pretend to only wear underwear, then this would be a funny trick in my opinion! XD
