Short shorts are a favorite even if not involving thongs. Interesting fun to see how short-shorts have evolved from the earliest ones like in the 1950s tune "Who Wears Short Shorts?" through the hotpants of the late 60s and 70s(think Cheryl Ladd in Charlies' Angels and of course Daisy Duke) on to the booty shorts of today favored by Lady Gaga, Miley Cyrus, etc. Even denim cutoffs that are thong length.
Short shorts used to rather rarely seen; now they pretty commonplace. Even senior citizen ladies wear them for jogging.
