Victoria Beckham has been a source of high style inspiration for the past three decades. She made us dream about “little Gucci marieprom dresses” during her Posh Spice days in the ’90s. Gave us the inspiration and confidence to chop our hair off and wear our most dangerous heels in the ’00s. And of course, made her incomparable aesthetic easier than ever to copy in this decade with her eponymous fashion line and makeup collaboration with Estée Lauder. But turns out she has some (scratch that, many!) style regrets and just got very candid about about her most infamous fashion phases. Trust us, you’re going to want to stop what you’re doing to read this now.

She penned a letter to her 18-year-old self for British Vogue in an effort to impart fashion advice and beauty wisdom before kicking off her highly-publicized adult life in the spotlight. In the letter she talks about marriage, plastic surgery, hairspray (and yes, her switch to sneakers!) and doesn’t leave any detail out. We picked out her her best fashion and beauty rules, below, so you can make 2017 your most Posh-inspired yet.

Own your plastic surgery procedures

She’s visibly gone up (and down) in cup sizes over the years, and ended up really regretting it. “I should probably say, don’t mess with your boobs,” she writes to herself. “All those years I denied it — stupid. A sign of insecurity. Just celebrate what you’ve got.”

Victoria and her hot husband David Beckham have been married for 17 years, and she credits at least part of that longevity to effort. “In marriage: have patience. Bite your tongue. Be supportive. And preserve a bit of mystique,” she says. “Never let yourself go completely (at least brush your hair, clean your teeth, have a bit of a brow going on because you will always want him to look at you and feel attracted).”

A little hairspray goes a long way

She tells her teenage self to let “her skin breathe” by wearing less makeup and warns her to never, ever let a makeup artist shave her eyebrows. But there’s one beauty addiction she’ll never overcome. “You will always be addicted to Elnett hairspray but you will tone it down. Less of the ‘Hello! I just got stuck in a wind tunnel’, please.”
