What is the function of this type of uniform? Quick to pull .. (OnlyFans)

What is the function of this type of uniform? Quick to pull down for the maid to let her Master suckle on. But the main feature is the skirt, to hide extra tools for her private convenience. The maid here are ordered to keep her butt closed and only for Master's usage to relief his lust.
