They typically seem to wear a warrior style of clothing they they have for every day use that is skimpy and usually have straps, as well as a bikini style briefs/clothing on their lower regions
or very short loin clothes. Many wear thigh length boots and stockings or have their legs completely bare. The style of clothing they wear would be considered otherwise "kinky" to normal people
but are worn freely by the women on the island. On top of this outfit, they often wear a long cape that reaches from the shoulders to the ankles. Workers seen in the fields and at other chores
without a cape, thus this proves the capes are not fixed permanently onto their outfits.
For evening and casual wear it was seen that they have a patterned shawl that goes over their top half but leaves the shoulders bare. They wear nothing underneath this shawl and it is tied together at the middle of the breasts with a single bow and often wear a mini-skirt on their lower half to match this or the usually bikini/loin cloth instead.
Warriors are seen each carrying a large snake wrapped around them. When the Kuja threatened Luffy, it was revealed that they use the snakes as bows.
