Re: what other brand girls underwear is similar to gymboree?
Can't speak for new, my DS is only 2 and not yet potty trained. But I have a ton of gymboree underwear that I got for dirt cheap in their clearance bins. I also have some baby gap undies that are awesome quality (can't speak for how they hold up yet since they aren't being used). If you have a store nearby, they have little bins by the register at gymboree and there are always tons of undies in there at the locations I shop at.
