How to Dress Your Kids Like Prince George and Princess Charlotte

Congratulations are in order. With a little brother or sister on the way and Uncle Harry and soon-to-be Aunty Meghan's wedding to dress up for, the royal toddlers are surely in need of a new wardrobe. Decked out in their signature retro style (think frills, knee-length socks, Edwardian smocked dresses and sensible shoes), the mini trendsetters have been known to cause a fashion frenzy with anything they wear selling out in minutes. Stay one step ahead and head to these London shops (or online stores) to dress your kiddos like royal heirs. Impeccable manners not included.

The sailboat dungarees worn by Prince George on his first official tour of New Zealand are still the most popular style at the 20-year-old, family-run store. Riley specializes in vintage-inspired designs, hand smocking and traditional prints—don't miss the Little Prince and Princess-themed Heritage collection designed in honor of the new heir to the throne. It's literally fit for a king.

What do you wear to a quick meeting with a head of state squeezed in 15 minutes past your bedtime? (A problem we've all had, no doubt.) Prince George handled this wardrobe dilemma flawlessly, showing up to meet former President Obama in a chic monogrammed dressing gown. The British company behind the robe also sells other personalized gifts including sleep suits, bibs, towels and blankets.

London-based Spanish designer Pepa Gonzalez makes smart and traditional clothes for newborns, babies and toddlers that are a firm favorite with the Duchess of Cambridge for big occasions like Pippa's wedding or, say, an official portrait with the queen. Vintage-inspired pieces like double-breasted cardigans and corduroy shorts for boys or frilly frocks with matching cardigans for little girls are all timeless (read: won't date in a photograph) and top quality.

The posh Chelsea shop is where Kate goes to buy T-bar shoes, velvet-trimmed peacoats and the hand-embroidered dress Princess Charlotte wore for her Buckingham Palace balcony debut. The retro European-style clothing and accessories are designed to make children look like children, so expect plenty of floral dresses, bows and big-collared blouses.

When it comes to her own wardrobe, the Duchess is a master at mixing high street and high fashion. So it comes as no surprise that she often turns to high street stalwart John Lewis (the Chelsea branch is known as Peter Jones) to dress the mini royals. You'll find essentials like the practical navy quilted jacket Prince George wore for his first day of nursery or something special like the lemon-yellow fair isle sweater Princess Charlotte wore to mark her second birthday.

The Spanish children's fashion brand known for simple and classic designs got the royal seal of approval when Princess Charlotte appeared in an official portrait wearing its paisley-printed dress. The good news is that the selection of traditional dresses, cardigans, short and dungarees on offer won't cost you a small fortune—the dress in question cost just $35. If it's good enough for a princess...

There is a branch of this London-based, family-run kids store just around the corner from Kensington Palace in case the Duchess needs to dash out for a pair of Italian leather shoes, a waistcoat, pinafore or the best-selling Guardsman knitted tank. Commoners that don't live nearby can order online.
