Anything which will be comfortable and classy
This is a joke right? You know what's even classier then those? A GARBAGE BAG! Maybe try scaling it down to something less revealing like jeans instead of leggings and just a nicer t shirt that covers your stomach. This is for the kids not for you tryin to get noticed.
The second one, little kids might look up your skirt and is a bit more classy in my opinion.
