She always wears these under skirts and dresses (or she wears skorts). They are pretty short, so not too hot in the summer. They sell some pretty good quality basic ones at JCrew, so I have a few pairs of those. They go on sale pretty regularly.
My three-year-old has always worn cartwheel shorts or bike shorts under her dresses or skirts, or skorts. Aside from the modesty issues (not something I worry a ton about at three), it's much more comfortable when she's swinging, sliding, and playing in the dirt or sand. I just buy a bunch of shorts in a variety of colors from whoever's having a sale. I also choose skorts over skirts to minimize bulk at the waistband.
