air-ee Cotton Square Neck Seamless Bra (Machine Wash Edition)

Regular price $42.90 SGD
Add to wishlist Compare

Meet the AIR-EE Cotton Square Neck.
The comfiest bra you know — reimagined in soft cotton, refined lines, and machine-wash ease.

For days that call for effortless comfort, elevated by design.

Softness that moves with you.
Made from 88% breathable cotton with a barely-there touch — smooth, light, and gentle on skin.
Feels like your favourite tee, made into a bra.

Naturally flattering.
The wireless silhouette gives medium support with a soft, rounded lift — invisible under clothes, yet always in shape.
Your second skin, now with a square-neck twist.

Designed for all-day wear.
Every detail fine-tuned for comfort: multiway straps that stay in place, a smoothing side band that hugs softly, and a 4-hook closure for your perfect fit.

Find your fit.
From XS to XXXL — because comfort comes in every size.

Model (Jaime) is Size 32/70B, wearing I'M IN Size S.

Care made simple.
Yes, it’s machine-washable. Because your comfiest bra should fit into your real life — not the other way around.
Wear. Wash. Repeat. Effortlessly.

The upgrade your top drawer’s been waiting for.
Discover the new AIR-EE Cotton Square Neck — seamless, soft, and ready to be lived in.

The difference between our OG air-ee square neck (signature edition) and our NEW air-ee cotton square neck (machine wash edition)
