Bra (ブラジャー) is a female undergarment meant to support a female's breast and is worn under their shirt. In Penguin Village, they can be bought at Briefers. Arale first learns what a Bra is in the chapter "Arale Goes on an Errand" from seeing Akane wearing one while she is changing. Akane described it to Arale as "panties for your boobs". A bra is actually first seen in "Kids Gone Wild" in the Dr. Slump manga.
