We know the Real Housewives of Beverly Hills look luxe on a regular basis, with all those designer duds and lust-worthy fashion senses, but have you ever wondered how much it actually costs to dress like a housewife and put together that extensive wardrobe? What about whose tastes are the most expensive? Kyle’s? Camille’s? Taylor’s?

Well, we put our tracking skills to the test and hunted down some cast-member approved pieces, tallied them up, and found out which of the ladies’ looks cost a pretty penny and who knows how to find a steal. Let’s play a game of cost comparisons, shall we?

Reunion: Kyle vs. Adrienne

Ah, the reunion special. There was plenty of drama there ... but, also, plenty of fashion. Which we loved! Kyle chose a deep-plum frock with split-sleeve detailing in which to sit down and tell all. Fellow cast member Adrienne looked equally glam in a rouched, curve-hugging number for the evening. Whose outfit costs the most dough, though? Adrienne takes this one. Her Badgley Mischka dress has a $720 price tag, whereas Kyle’s Haute Hippie look clocks in at about $420.

WINNER: Adrienne

Everyday: Kyle vs. Taylor

As many red-carpet events as the housewives attend, they still make time for some shopping and socializing. (Obviously!) Which lovely lady spends the most on her everyday wardrobe: Taylor or Kyle? Kyle’s Vince sequined tee’s cost isn’t exactly economical, but it’s not too bad (for a Beverly Hills-er), either. It rings up at $340. But the Devi Kroell bag? That’ll put you out a whopping $2,490. Needless to say, Taylor’s look doesn’t come very close. Her Robert Rodriguez tank dress is a mere $240.

WINNER: Kyle

Red Carpet: Kyle vs. Camille

At Bravo’s Upfront Presentation, Kyle looked pretty in emerald while Camille donned a gray-and-white printed frock. Both were glam and gorgeous, but whose look really breaks the bank? That would be Camille’s. By a long shot. Her Gucci frock cashes in at $1,850. Kyle’s Donna Morgan dress retails at just $175.

WINNER: Camille
