Fancy, expensive clothing, used usually [[ConspicuousConsumption to show off the wealth]] of either those wearing the clothes or who bought the clothes for them, because [[GarnishingTheStory looking cool and/or pretty]] isn't cheap.
Sometimes these outfits are fancy enough to be CostumePorn, which [[Administrivia/TropesAreFlexible can range between]] outfits that are [[SimpleYetOpulent elegantly simple]], to outfits so overdone they become ImpossiblyTackyClothes (and some [[IWasQuiteAFashionVictim fancy clothes of the past can seem that way]]).
