Kotohime's two outfits are complimentary
Standard has great upper body & oppai potential, works great in intimate scenarios at home, and generally is well suited for showing bare body parts, tabi at most.
Police getup is good for lower body, low angle shots, office lady-esque tropes, tights, black lingerie, and there's a different chemistry going in with her outfit having all 3 primary colors.
Mix and matching also gives pretty good results. Kotohime's just that good.
