The girls being put forward to Alexander were all dressed in a very similar way to how those four girls before were- bras or sashes on the top, combined with thin, linen underwear and revealing pants below, thus showing or nearly showing everything that a man might want to see in a pleasure slave.
Their hair was done in all kinds of various ways- braided, ponytailed, free flowing, bunned, to name only a few and they wore various ornate jewelry, such as bangles, anklets, earrings, and neckpieces, as well as sexy chains around their breasts or lower hips.
Seeing this opulent display of ornaments, Alexander would have to admit, that he might have underestimated the costs of dressing and maintaining these girls.
Gold itself was expensive, and when it was worked on by skilled artisans like now, even just a little bit, it quickly tripled or even quadrupled.
