The layer that makes everything sit better
You know the outfits that would be perfect if it were not for a seam showing through, or a waistband digging in by mid-afternoon. The Invisible Seamless Bodysuit is the quiet base layer that solves it: a soft, seam-free second skin that smooths everything under your clothes so they fall the way they are meant to.
Why women reach for this
- Truly invisible. Seamless edges and a smooth knit mean no lines showing through dresses, skirts or fitted tops.
- Comfortable hold. A gentle medium hold smooths your silhouette without pinching or rolling.
- Wire-free comfort. Soft, unstructured support you can genuinely forget you are wearing.
- Loo breaks made easy. An open gusset means you can nip to the loo without taking it off.
Made to fit real plus-size figures
A stretchy, seam-free knit that moves with you, in sizes S to 4XL. Have a look at our size guide to find your best fit — and if you are between sizes, size up for the most comfortable wear.
Fabric & care
Made from a breathable blend of polyester, cotton and elastane. Machine wash cool on a gentle cycle, do not tumble dry, and skip the fabric softener to keep the stretch at its best.
Good to know
- Wire-free, cupless design — wear it with your own bra.
- Medium comfort hold — it smooths under clothing rather than compressing.
- Free UK tracked delivery on orders over £40.

Slip it on under your favourite outfit and let everything just sit right.
