Tube Bra

In-game Shop: Jackets and Shirts -> Shirts
Price: 300 FC single character  /  375 FC account wide.

Note: As usual, some of the naming is goofy, e.g. “red with black dots” has white dots, and the “white with black stripes” and “red with black stripes” are both black bras. So read and look at previews carefully before clicking buy. :)
