Here, we have the Shimmer-Sentry family (double S family), and we've got Captain Flash Sentry of the Equestrian Royal Guard, Mistress Phoenix Guardian Shimmer-Sentry, Master Warden Shine Shimmer-Sentry, and of course, Mrs. (right now a teenager in this pic, but these two kids are time-travelled, so it's either Ms. or Mistress) Sunset Shimmer-Sentry. As you know, this unicorn-pegasus family loves to guard Ponyville. Because they're Martial Arts Kids, duh.

Flash Sentry wears a pair of boxing shorts with a pair of cycling shorts underneath, a pair of socks and a pair of sneakers, Phoenix Guardian wears a sports bra with a bandeau bra underneath, a pair of boxing shorts with a pair of capri leggings underneath, a pair of socks and a pair of sneakers, Warden Shine wears a pair of boxing shorts with a pair of cycling shorts underneath, a pair of socks and a pair of sneakers and Sunset Shimmer wears a zipper sports bra with her own bikini top (a bra) underneath, a boxing skirt with a half-slip and a pair of capri leggings underneath, a pair of socks and a pair of boxing boots.
