Usually worn by attractive female warriors to maximize exposure of body parts such as cleavage, midriff, buttocks, hips, legs, etc. The top part covering the breasts is either a bikini top or, more commonly, is usually shaped much like a bikini top but with some obvious metal reinforcement marks. The bottom may be a bikini bottom, a short loincloth, a long loincloth, a skirt, full pants, or possibly some combination. Armored boots and capes can be expected, along with options like helmets, gauntlets, elbow pads, knee pads, shoulder pads, power suits, etc.
Naturally, and ironically, less coverage usually means less protection from attack, so one would think that bikini armor has an inherent magic to apply the inverse relationship between coverage and protection.
