Sunspel x Mandarin Oriental Hyde Park

In a collaboration that leans into British heritage without shouting about it, Sunspel and Mandarin Oriental Hyde Park, London have joined forces for a limited-edition drop that celebrates refined simplicity. The product? A bespoke version of Sunspel’s iconic Classic T-shirt, rendered in the hotel’s signature Celadon green — available exclusively to guests staying in its Signature and Speciality Suites throughout July 2025.

This isn’t a case of slapping a logo onto a tee. It’s about precision, provenance and craftsmanship. Sunspel’s Classic T-shirt has long been a staple for those who appreciate their wardrobe essentials quietly excellent. Crafted from extra-long staple Supima cotton sourced from a single Californian farm, the fabric is durable, breathable, and lightweight — a balancing act that’s hard to pull off. But that’s the Sunspel way.

Produced at the brand’s Long Eaton factory — the heart of its operations since 1937 — each T-shirt is cut, sewn and finished by artisans who’ve spent decades refining the process. We’re talking 12 production steps and 15 quality checks. The end result is a T-shirt that feels less like a basic and more like a benchmark.

This collaboration takes that craftsmanship one step further. In addition to receiving the Celadon green exclusive, guests at Mandarin Oriental Hyde Park will be invited to take part in Sunspel’s Bespoke T-shirt service. That means they’ll have the chance to commission a one-of-a-kind garment from the brand’s full range of globally sourced luxury fabrics — cut, tailored and handmade to their precise specifications.

There’s a quiet synergy here between the two brands. Mandarin Oriental Hyde Park has made a name for itself not just as a luxury destination, but as a custodian of timeless elegance. Sunspel, meanwhile, does the same for your wardrobe. Both are understated in the best sense of the word: confident without being loud.

For those not checking in, the limited-edition T-shirt will be on display at Sunspel’s Jermyn Street flagship for one week only from July 1st — a fitting setting given the street’s storied menswear legacy.
