Swimwear Size Guide | Swimwear For Small Busts

Activewear size guide

At LOU, we believe high-performance compression shouldn’t mean a total disappearing act. We’ve traded the "pancake effect" for intelligent support that contours and defines rather than flattens. It’s about getting the lockdown feel you need for a PB, with a fit that actually respects your natural silhouette.

As an additional guide to help you find your perfect fit, our models' measurements (bust, underbust, hips and waist) are listed on each product page they are featured in.

Use our size finder below to find your perfect size or contact us at info@louswim.com

SWIM SIZE GUIDE

BRA SIZE GUIDE

Intelligent Compression

Fed up with high-support bras that flatten you into a pancake? You shouldn't have to sacrifice your silhouette for a secure lockdown.
Our targeted compression contours and defines, providing incredible support without the crushing effect. It's engineering that respects your frame, keeping you steady during every movement.
Contoured Support

High performance shouldn't mean a total disappearing act. We trade flattening compression for intelligent shaping that celebrates your lines.
Integrated shaping (no bulky, shifting pads) preserves your natural shape while delivering the precise hold and stability you need for peak performance.
Active Comfort

To perform at your best, you must first be comfortable. Our seamless construction and premium LYCRA®-infused fabric ensure a perfect, skin-hugging fit that moves with every rep.
With a velvety-soft finish achieved through a specialised German water-brushing process and a lasting cool-to-touch sensation, this gear is designed to feel like a second skin while staying fresh and maintaining its shape.

Frequently Asked Questions

HOW IS LOU FIT DIFFERENT TO OTHER BRANDS?

We design exclusively for smaller chests with thoughtful cuts, flattering fits, and supportive details that celebrate your shape with sewn-in push-up padding.

I HAVE A SMALLER CHEST BUT FULLER FRAME. WILL YOUR PIECES STILL FIT ME?

Yes! Our styles are designed to fit and latter a range of body types with smaller busts. Check our size guide for both band and body measurements to find your perfect fit.

DO YOUR TOPS HAVE PADDING?

Yes! All our tops include sewn-in, push-up padding that offers subtle lift and coverage, enhancing your natural shape while supporting you during your fitness activities.

I'M EXTREMELY SMALL-CHESTED, DO I NEED TO SIZE DOWN?

No, sizing down is generally not necessary. Our pieces are designed with smaller busts in mind, and sizing down may result in an overly tight fit. We recommend following the size guide for the best fit, but if you’re unsure, feel free to contact us for personalised advice.
