Most flattering matching gym set

Introducing gym wear that’s equally at home in a spin class or a coffee shop. Our seamless sets are tried-and-tested winners across our underwear department, but did you know that we also have seamless gym sets? Crafted to sculpt and accentuate your figure without showcasing those VPLs, our seamless range is the activewear version of day to night dressing — workout to hangout!

Best cold weather matching gym set

Caught the running bug? Or maybe you’re still a firm advocate of the daily walk, post-pandemic? Either way, exercising outdoors in autumn/winter, (sadly) means always factoring in the weather — but don’t fret, our affordable activewear promises the perfect hybrid of fashion and functionality.

The key to A/W activewear is all in the layering and our lightweight sports jackets are a staple for runners of all abilities. Their quarter zip design is great for temperature regulation, the large front pocket is great for storing electricals for a hands-free run, and the drawstring hem is great for cinching or loosening for your desired coverage. Lastly, it’s compact enough that it can be stuffed into your running vest mid-run or rolled up and put into your tote bag during any unseasonably warm matcha dates!

Best matching gym sets for yoga

2024 was a popular year for hot yoga and reformer Pilates, and they’re not going anywhere for 2025! Shop yoga outfits across the entire range, most notably through our seamless range with its high waisted leggings and matching vests that hold you in as you stretch, bend and balance. Got a Pilates lover in your life? Gifting them our grip sole socks is a no-brainer!

Most stylish matching gym set

Move over burgundy matching gym set, the 2025 must-have has arrived! Our mauve-toned buttery soft pieces are set to be bestsellers, so you’ll have to be quick if you want to get your hands on them! The capsule includes: a flattering, ruched-front crop top, short sleeve cropped tee, zip-through jacket, full-length, high-waisted legging and high-waisted sports shorts.

Most versatile matching gym set

If you’re looking for versatility, our seamless black matching gym set ticks all the boxes. Flattering, fuss-free and fit for exercising or errands, we know it’s only a matter of time until you stock up on the other colourways too! 

Best supportive matching gym set

Seeking a style that supports you as your exercise? Our seamless contour range is designed to leave you feeling secure, while flattering your physique. The four-way stretch capabilities mean it moves with you as you stretch and extend your muscles but then springs back and contours to support your body as you contract and relax them.

Best flared matching gym set

Fashion is quickly finding it’s place within the activewear space, because trends aren’t just reserved for day-to-day wear. A prime example? The flared yoga legging. Combining an iconic 70s trouser silhouette with the comfort and flexibility of activewear, there’s a reason that the line is blurred when it comes to when and where people are sporting them. Team with the cropped tees, vest tops, sports bras from the range, or similar styles from your daily wardrobe. 

Best breathable matching gym set

Most of our performance pieces are designed with moisture-wicking fabrics to keep you cool and comfortable as you exercise. So, will it be our buttery soft sets, seamless matching must-haves or yoga-style pieces that you’ll be adding to your basket?

Best short matching gym set

Despite the colder temperatures, we know that a gym short set is a staple in every activewear wardrobe. Weekly weight sessions? Our seamless shorts and sports bra duos are ready! If you’re not sure which sports bra style to go for, our handy sports bra guide has all the answers.

What to look for when choosing women’s gym sets

Selecting the right gym set can enhance your performance, comfort, and style during workouts. Here's a guide to help you find the perfect one:

1. Comfort and fit

Snug but not restrictive: Look for gym sets that offer a fitted silhouette without digging into your skin.

High-waisted leggings: Provide support, stay in place during movements and enhance confidence.

Adjustable features: Tops with adjustable straps or bras with customisable closures allow for a more personalised fit.

2. Fabric quality

Moisture-wicking materials: Fabrics like polyester, nylon, or spandex keep sweat away from the skin, making sure you stay dry.

Four-way stretch: Enables flexibility for dynamic movements like squats, lunges, or yoga poses.

Breathable and lightweight: Mesh panels or perforated fabrics enhance airflow.

3. Support

Built-in sports bras: A top with built-in support is ideal for low- to medium-impact workouts.

Seamless designs: Reduce chafing and provide a second skin feel for activities like running or high-intensity training.

4. Style and versatility

Matching sets: Create a cohesive, polished look while offering versatility to mix and match with other workout pieces.

Variety of styles: Options like crop tops, vest tops, or long-sleeve tops ensure there’s a set for every preference and activity.

Trendy colours or patterns: Choose designs that match your personal style to keep you motivated.

5. Durability

Stretch retention: Ensure the fabric doesn’t lose its shape after multiple washes or intense stretching.

Opaque materials: Avoid see-through leggings by checking for squat-proof fabrics.

6. Activity-specific features

High-impact workouts: Opt for compression fabrics and high-support bras.

Yoga or Pilates: Look for softer, stretchy fabrics with minimal seams for ease of movement.

Outdoor training: Consider sets with UV protection or moisture-wicking features for comfort in various conditions.

7. Practical features

Pockets: Leggings or shorts with side or hidden pockets for essentials like keys or cards.

Flatlock seams: Prevent irritation and chafing.

Quick drying: Essential for those who need to transition quickly post-workout.
