Overview

This seamless push-up bra gives you lift and shape without the lines and seams that show through a fitted top. The soft, stretchy fabric follows your body like a second skin, while the push-up shaping lifts and holds your bust for a rounded, balanced look.

It's cut to smooth the underarm area too, and the wide U-shaped back sits flat for a clean line from every angle. The fabric is breathable and air-permeable, so it stays comfortable through a long day.

Size guide

Choose your band size. The cup is one size and the fabric stretches to fit your shape.

Band size	Also shown as	Cup
M	M	One size
L	L	One size
XL	XL	One size
XXL	XXL	One size

4XL	4XL	One size

How to measure: wrap a soft tape snugly around your ribcage just under your bust, then loosely around the fullest part of your bust. Compare with bras that fit you well and choose the band size you usually wear. If you're between two sizes, choose the larger one for comfort.

Support where it counts

Four ways it shapes your outline

The bra works on more than the cups, so the whole line of your top looks smooth.

Lifted bust

Push-up shaping that lifts and holds for a rounded look.

Smoother underarms

Shaping at the sides that smooths the underarm area.

Balanced shape

A firmer-looking, balanced bust under any top.

Flat back

A wide U-shaped back that sits flat and stays put.

Shaping support

A firmer-looking, balanced bust

The bra is cut to lift and hold your bust and to smooth the area under your arms, where many bras leave a bulge. That gives you a neater, more balanced outline under fitted clothes.

The soft, stretchy fabric holds its shape against your body, so your top can sit smoothly over it.

Breathable comfort

Fresh and light all day

The fabric lets air flow through, which helps prevent heat and moisture building up. Your skin feels fresh and dry, even on a long day.

It's soft, light and gentle against your skin, so it's easy to wear every day.

FAQ

Questions, answered

How is it different from a classic push-up bra?

It's seamless, so there are no seams or hard edges to show through your clothes. It still gives a push-up lift, but with a soft, stretchy fabric and a second-skin feel. It also smooths the underarm area for a neater outline.

How do I choose my size?

Choose your band size from M to 4XL. The cup is one size and stretches to fit. Measure under your bust and around the fullest part, compare with bras that fit you well, and choose the larger size if you're in between.

Is it suitable for all body types?

The stretchy, ergonomic design adapts to different shapes and comes in six band sizes. If you have a very full bust, choosing a larger band size often gives a more comfortable fit. Measure under your bust before you order and compare with a stretch bra that fits you well.

Can I wear it all day?

Yes. The fabric is breathable and elastic, so it stays light and comfortable through a full day. It's designed for everyday wear, from work to the evening.

Will it show under tight clothes?

It's designed to stay discreet. The seamless edges lie flat and the wide back sits smoothly, so it hugs your shape without leaving lines. Under very thin or light tops, choose the colour closest to your skin tone.

Does it help with posture?

It's a comfort and shaping bra, not a posture or medical product. The wide U-shaped back is designed to sit flat and feel supportive, but it isn't made to change how you sit or stand. If you have back problems, speak to your GP or physiotherapist.

Which colours can I choose?

It comes in Black, Blue and Ivory, plus several mixed colour options such as Black Ivory Blue and Blue Ivory Green. Check the colour option list for every combination.

What is it made of?

It's made from spandex and nylon. The fabric is stretchy, soft and breathable, which gives it its second-skin feel and helps it adapt to your shape.

How do I wash it?

Wash it gently and follow the care label inside the bra. Reshape the cups while it's damp and let it air dry. Gentle care keeps it soft, elastic and supportive for longer.

How quickly will my order arrive?

Orders are prepared within 1 to 2 business days and shipped with a tracking number so you can follow your parcel. Full details are in the Delivery & returns tab.
