Vintage shopping can be a bit hit-and-miss – with a dust-induced sneezing fit more probable than striking gold. But it's a different ballgame completely with William Vintage.

Sourced from private collectors globally and curated by newly appointed CEO, Marie Blanchet, you can bank on the London-based boutique to deliver the goods. And by goods, we mean rare one-of-a-kind and haute-couture pieces – from 1950s Dior and 1960s Saint Laurent to 1990s Gianni Versace.

Collaborating now with Matches Fashion, William Vintage presents a 28-piece strong edit that houses a treasure trove of exquisite and seminal designs. Think YSL's 1991 Le Smoking three-piece suit and Dior's 1955 Mexico faille gown, which represented the house's 'New Look' silhouette.

Intrigued to hear from the experts, we asked Marie and Matches Fashion's Fashion and Buying Director, Natalie Kingham, to cherry-pick their favourite designs.

Marie Blanchet, CEO of William Vintage
What? YSL 1991 Le Smoking three-piece suit.
Why? "Yves Saint Laurent is my favourite designer of all time – he created the modern woman's wardrobe and we are still playing by his code. The haute couture three-piece smoking suit is the ultimate Monsieur Saint Laurent piece, which inspired decades of women's tailoring. If a woman was to own one vintage outfit, to me, it would be this one!"

Natalie Kingham, Fashion and Buying Director of MATCHESFASHION.COM
What? Yves Saint Laurent 1968 Safari gabardine suit.
Why? "I love all of the seventies looks we have bought, especially the pieces from the Saint Laurent safari collection. The collection is so evocative of the mood of the era – this suit is probably my favourite look from our edit and I know when I wear it I will feel steeped in fashion history yet still incredibly modern."
