The gameplay mechanic here, aside from it being an equip screen, is the wear-with-all award allowing her to equip the muscle belt.
The more literal translation of the award is something along the lines of "wayfarer's medal." I used the in-game english names for the equipment here as they make more sense in context.
E: Mitre
E: Muscle Belt
E: Sizzling Bikini Bottoms
E: Wear-With-All Award
