Also known as: ジャージメイド, 运动服女仆
An Unconventional Maid costume that utilizes a Track Suit or a Track Jacket as the base.
May be simply a longer Jacket worn like a dress, a skirt and jacket combo, or a Track Pants + jacket set, but the costume needs some maid-like elements, like a Maid Apron or a Maid Headdress.
Note that "jersey" in Japanese refers to a Track Suit and not the "jersey" in English, do not tag these as Jersey.
