At a Glance:

Our CC09 is our most authentic 1940s-style bra, and that authenticity isn’t for everyone. It creates a true period-correct, pointed silhouette: fit and shape expectations were very different in the 1940s compared to today.

Because of this, it has one of our higher return rates for “item doesn’t fit.” In most cases, it’s the shape rather than the size. Please do check the measurements in the product description carefully before ordering. That said, it’s rated ★★★★★ 4.8 out of 5 — so you’ll likely either love it or hate it!

The band for our satin 1940s Bra has very limited stretch. 

This soft cup bra features traditional band sizing and barely any stretch, just as it would have in the 1940s. The cups are shaped to create a natural, period-appropriate silhouette, while delicate nylon trim beneath the bust adds a subtle, feminine touch. Non-stretch ribbon straps and minimal elastic at the back complete the authentic construction, making this bra a must-have for vintage purists and fashion historians alike.

Made from 100% polyester satin in a peach tone reminiscent of original underpinnings, the CC09 bra is designed to be worn as part of a full set with our matching French knickers or high-waist pieces from our peach lingerie ranges.

The CC09 style, named after its 2009 launch, pays tribute to the CC41 Utility Scheme, introduced during wartime rationing to ensure quality and durability in British fashion. While we don’t follow fabric restrictions to the letter, we’ve stayed true to the spirit and design of original CC41 lingerie—bringing you a bra that looks and feels as close to the real thing as possible, while using modern materials for long-term wear.

Each CC09 bra is ethically crafted in our trusted Indian factory, where our vintage-inspired pieces are sewn with care by skilled machinists.
