Arum

Every minute, a customer in France chooses Arum. Instantly recognisable by its signature floral lace and feminine lacing detail, this Arum bra has become the go-to piece from Sans Complexe Paris for women with a fuller bust. Available as an Arum brief, Arum thong and even as a full set, Arum flatters every figure with the same promise: support and femininity, perfectly balanced.

Arum, the must-have bra from Sans Complexe Paris

Support designed for a fuller bust (cup B to J)

Arum's strength lies in its technical construction, designed from the outset for a fuller bust. The cups, made with a 3-panel construction, follow the natural shape of the bust and distribute support evenly without creating uncomfortable pressure. A tulle lining reinforces support while keeping the lace light and delicate.

The hook-and-eye U-back stabilises the whole bra and stops the straps from slipping throughout the day. In our signature colours (Black, White, Royal Blue), the size range runs from cup B to cup J, with construction specifically adapted on the larger cups (H, I, J) to guarantee the right level of support.

Refined lace, designed for comfort

The underwired floral lace bra Arum never sacrifices comfort for style. The stretch lace adapts to every bust shape, while the sides and back, made from soft microfibre, feel like a second skin. The lacing details and small bows at the centre front define the unmistakable Arum style, without ever compromising on support.

To complete the look, the Arum brief and Arum thong carry the same signature details: floral lace, side lacing and a cotton-lined gusset for everyday comfort. Head to our plus size briefs to find the matching pieces.

Colours and variations available

Arum comes in a wide palette designed for every style: Black and White, timeless and available up to cup J, as well as bolder shades like Royal Blue, Magenta Purple, Tangerine Orange, Peach Pink or Aqua Green. Print lovers will find the Arum Mosaïc line, with its floral and graphic patterns, while the Party Black-Copper and Cabaret Black & Pink versions bring a more festive touch to the collection.

How to choose your size in the Arum collection?

Choosing the right size is essential to get the full benefit of Arum's support and comfort. Your band size is measured just under the bust, while your cup size is the difference between that band measurement and your bust measurement at its fullest point. If you're torn between two sizes, it's generally best to go for the larger cup with a snugger band, for optimal support without any pinching. To leave nothing to chance, check our bra size guide, which walks you step by step through measuring and size conversions.
