1. Thou Shalt Not Wear Bright Lipstick
There's a reason why you'll never see the Duchess rocking a bold red lip, or a bright berry colour—it isn't really in protocol to go above nude or pink. Although Queen Elizabeth has a signature pink lip, the rest of the royal court steers clear of bright colours. It also has the added benefit of making sure she never has lipstick on her teeth.
2. Thou Shalt Not Have Bright Nails
Queen Elizabeth is known for her distaste of bright manicures and very long nails; therefore the Duchess always keeps her nails short and in a clean semi-nude colour. She shares a favourite polish with the Queen, Essie's 'Ballet Slippers.'
3. Thou Shalt Keep It Simple
Even though you might see her add a smoky eye or an extra lick of mascara for a night-time event, Catherine rarely does 'heavy' makeup. Between her medium-coverage foundation and light eye makeup, the Duchess usually keeps things simple, and never goes overboard with blush, eye shadow, or lipstick. This keeps her from looking 'overdone.'
4. One's Makeup Must Stay Put
When the Duchess is attending an event, she can often be there for hours and is often doing activities while there. This means that, throughout the day, her makeup and hair must stay flawless. Achieving this requires a few tricks, including a very good setting powder to keep her from getting shiny, a good setting spray to keep everything in place, and a sneaky hairnet to keep her up-dos from unravelling.
5. Thou Shalt Switch It Up
When it comes to her hair, Catherine never keeps it the same way for long. Over the past several years in the spotlight, Duchess Catherine has gone from long waves, to shoulder-grazing curls, to a fringe, and a deep side part. The constant switching-up means she always has a fresh look.
6. Thou Shalt Banish Thy Greys
Once or twice, the mother-of-three has been spotted sporting some errant grey hairs, but they're never there for long. Catherine's usually lets her colourist take care of those pesky greys so she can keep her glossy brunette waves looking picture-perfect.
7. Thou Shalt Never Look Unkempt
This one is a relative no-brainer. When she is out on an engagement, Catherine is representing the Queen, so she always has to look put-together. This means no un-styled hair, no makeup-less face and no messy ballet-buns.
