Royally Obsessed: Kate Middleton's Go-To Lipsticks

This is the lipstick color we almost always see Kate Middleton wearing. It's a slightly pink-leaning nude shade that has some sandy undertones.

We have confirmation that Bobbi Brown's Lip Color in Sandwash Pink ($29) is a lipstick that Kate Middleton keeps handy and wears often.

Another great option that's easy on your wallet is Sephora's #Lipstories Lipstick in Tan Lines ($8).

This uberfeminine shade of pastel, petal pink feels equal parts modern and retro. It's a great go-to for spring, or anytime you want to embrace your girlishness.

CoverGirl Katy Kat Matte Lipstick in Pink Paws ($7) has a demimatte finish that channels that same sort of retro-mod vibe.

MAC Cosmetics Matte Lipstick in Mehr ($17.50) is ever-so-slightly darker, but features that same pale pink hue with blue undertones.

For a splurge-y option with a satin finish, try Chanel Rouge Allure Luminous Intense Lip Colour in Seduisante ($37). It goes on a touch lighter than what it seems in the picture.

There's never a minute when Kate doesn't look fabulous, but when she gets real gussied up — say, for a royal event — she pulls out all the stops with a subtle but gorgeous mauve.

Rodin Olio Lusso Luxe Lipstick in Heavenly Hopp ($38) is a warmed, nude hue that's not too brown or too pink.

COL-LAB Full Body Lipstick in Really? ($11) offers a pink-leaning mauve in a matte finish.

For the prettiest mauve-pink lipstick with a satin-matte finish, swipe on Kat Von D Studded Kiss Crème Lipstick Lovecraft ($19).
