Pippa Middleton's £2,000 bikini parade: Kate's sister stuns in very expensive swimwear and accessories on holiday to St Barts

Pippa Middleton is known for her exquisite fashion sense, which clearly extends to her swimwear choices.

The mother-of-three showcased a covetable collection of bikinis worth £1,000 during an exotic getaway in the Caribbean with her husband James Matthews and their children last week.

Pippa, 40, started her journey in style, selecting two swoon-worthy bikinis from luxury swimwear label ViX, including the iconic £194 'Bia' style, which was previously spotted on sister Kate Middleton.

Additionally, Pippa showed off two vibrant Heidi Klein bikinis, priced at £230 and £280, as she enjoyed the Eden Rock beach, owned by her husband's family, in St Barts.

The Princess of Wales's younger brother, who played with her daughters and dived in the sea with her son, received three pairs of designer sunglasses worth a total of £745.

Last week, Pippa Middleton showed off her very toned physique as she enjoyed a beach day with her husband, James Matthews, and their kids.

Pippa started the trip in style, choosing a £190 white ViX bikini set for a day on the beach at Eden Rock, owned by her husband's family, in St Barts.

The two-piece triangular 'Paula' piece featured the brand's signature handmade button detailing, interwoven with 24-carat gold beading.

US-based ViX was founded in 2000 by Paula Hermanny and has built a celebrity following that counts Kate Hudson, Izabel Goulart, Candice Swaenpoel and Gisele Bündchen as fans.

Pippa tied her brunette locks into a bun and paired her bikini with round tortoiseshell sunglasses, creating an effortlessly chic aesthetic.

The practical mum wore minimal accessories for her family day out, simply opting for a white watch to complement her bikini.

Pippa also showed off a £194 emerald bikini from ViX with £289 Jimmy Choo sunglasses

Pippa changed into the equally seductive Heidi Klein 'Stella Maris' bikini, which cost £230, with Ray-Ban sunglasses

Pippa and her husband, James Matthews, are staying at his parents' exclusive hotel, Eden Rock, on the sun-drenched island.

And his wife looked suitably glamorous at her next appearance, opting for a £194 emerald green bikini from ViX and £289 Jimmy Choo sunglasses.

Arguably ViX's most iconic design to date, the 'Bia' style has been worn by Salma Hayek, Coleen Rooney and Kim Kardashian – and was even spotted on Kate Middleton in 2013.

The flattering halter top is made from the brand's signature Brazilian lycra and embellished with 24k gold-plated sliding tubes that also adjust the fit.

Pippa later changed into the equally seductive Heidi Klein 'Stella Maris' bikini, £230, paired with Ray-Ban sunglasses, which cost £142.

This classic triangular silhouette features a charming blue and white floral print, braided details and gold branded hardware.

On Sunday, Pippa was pictured wearing another Heidi Klein bikini, which cost £280, with a matching tunic cover-up costing £295.

She wore Chanel's sold-out brown CH5387 sunglasses, which cost £314.

The standout look featured Heidi Klein's brand new two-piece 'Waldorf Winds' piece, created in a peach and white color palette.

The flattering design features the label's signature deep halter neck and striking gold hardware.

The London-based label, founded in 2002 by design duo Heidi Gosman and Penny Klein, has been a favorite of Pippa's for a number of years.

Pippa and James looked every inch the doting parents to their three children: Arthur, five, Grace, two, and Rose, one.

The Matthews family owns the Eden Rock resort on St. Barts, one of the most exclusive hotels in the region. Stars such as Elton John, Brad Pitt and Leonardo DiCaprio have stayed at the resort.

James' parents, David and Jane Matthews, moved to St. Barts in September 1995 after purchasing Eden Rock from local adventurer Rémy de Haenen.
