Sometimes these outfits are fancy enough to be Costume Porn, which can range between outfits that are elegantly simple, to outfits so overdone they become Impossibly Tacky Clothes (and some fancy clothes of the past can seem that way).
Or they can range from higher quality versions of normal clothes, to an Impractically Fancy Outfit.
Heck, in the past, even certain colors could make clothing opulent due to the rarity of natural dyes.
Now some of these tropes can include lower cost versions (which is common today in Real Life), but "the good stuff" is still opulent.
