SIZING ADVICE

Choose your usual dress size, then usual cup size. If you already own our Busty Basics Tops, go with the same size in the Movement Tank.

If you’re between dress sizes (Eg, 10/12), size down in the body.

If you’re between cup sizes (Eg, FF or G), size down in the cup.

The activewear tank designed specifically for busty ladies.

With a sleek design, cup size incorporation, and compressive fit, the Movement Tank was made to deliver second-skin comfort and gentle support for all-day wear. Like all of our clothing, the Movement Tank takes your bust size into consideration, cut with proportionally more space in the chest area than standard active tanks. Wear it braless for low-impact activities (think: yoga, pilates, light walking), or layer it over your favourite bra for additional support.

Please note, the back of the tank now overlaps the back of the Movement Shorts and Pants.

Our models wear the Movement Tank without bras.

FEATURES

Low impact support on its own, or layer it with the Movement Sports Bra for extremely high impact (think: netball, touch football, AFL, etc).
Lightly compressive, holds-you-in fit
Double-lined construction for zero transparency
Curved front hem to pair perfectly with the Movement Pants or Shorts and keep your midsection covered.
Premium Italian-made performance fabric

FABRIC & CARE

60% Recycled Polyamide
40% Elastane (excludes lining and trims)

For maximum longevity, hand wash only is recommended. Do not bleach. Line dry out of direct sunlight. Do not spin dry, iron, or wear on rough surfaces.

How to Measure

1. Overbust

In a non-padded, preferably underwired bra, measure around the fullest part of your bust, holding the tape measure gently against your body.

2. Underbust

Measure firmly around your ribs, just below the roots of your breasts, keeping the measuring tape parallel to the floor.

3. Waist

Measure around the smallest part of your natural waist, usually near the bottom of your ribcage.

4. Hips

Measure around the widest part of your hips and bum, keeping the tape measure parallel to the floor.

Customer Reviews

Overall rating: 4.5 / 5 from 11 reviews.

The tank fits really well and is comfortable to wear. I only wish it was a little longer, as it rides up and exposes my tummy whenever I lift my arms. A bit of extra length would make it perfect!

Elana O. 4/5 Verified October 15, 2026

Movement Tank

Strange fit- long at the front and super tight under sports bra. But wilæ wear sans bra.

Lydia M. 2/5 Verified August 17, 2026

MOVEMENT TANK

Obsessed with the fit. Feels like a second skin, the girls are contained and aren’t squished for once, nothing spilling out. Buttery soft fabric. I could live in this.

Yasmin S. 5/5 Verified July 23, 2026

I’ve never not had to wear a bra until now! Such a great top!

Comfy as, can roll up when I'm working out though. Comfy enough to wear on its own around the house too.

Love it! I ended up sizing up in the bust area as I was hanging out of my usually fit a little too much.

January 6, 2026

I'm an 8H/J with a very full and heavy bust and I have never been able to wear just a sports crop to yoga or pilates before without falling out either the top or the sides after 5 mins. So I usually have to wear a shirt on top of a bra which is horrible during heated classes and summer. I can't believe how well this crop holds me in but also looks really great at the same time. So so happy with this purchase !!!

The fabric is beautiful. The fit is so comfortable. And I feel amazing. Couldn’t be happier. It’s doesn’t squash my boobs which is also pretty awesome.
