Athleta: Stylish Activewear That Doesn’t Always Fit the Same

Athleta, the performance-lifestyle brand owned by Gap Inc., has gained huge popularity for its blend of high-performance fabrics and flattering cuts. Whether you’re looking for leggings, workout tops, or recovery loungewear, Athleta caters to an inclusive size range and a variety of fits.

But here’s the issue: Athleta’s sizing can feel inconsistent, especially for UK shoppers navigating US sizes, stretchy fabrics, or different fits like “sculpt”, “relaxed”, or “contour”.

That’s where Tellar.co.uk comes in. We help you match your actual body measurements or known sizes from other brands to your perfect Athleta fit in seconds. It’s fast, free, and eliminates guesswork across 1,500+ brands.

Do Athleta Clothes Run Small, Big, or True to Size?

Athleta sizing tends to vary by product category:

Item Type	Fit Tendency
Leggings	True to size
Joggers	Relaxed fit – size down for compression
Sports bras	Run small (many size up)
Tops & tanks	Slightly large (roomy in bust)
Swimwear	Slightly small in bust + hip

US sizing may also cause confusion for UK shoppers. For instance, a US size 6 = UK size 10, but fabric stretch and design cut can still affect actual fit. Tellar handles these conversions automatically.

Common Fit Questions About Athleta (UK Perspective)

Q: How do Athleta leggings fit compared to Lululemon?
A: Athleta’s leggings are more forgiving in the waistband but slightly roomier overall. Tellar will recommend whether to stick to your Lululemon size or go down for a sculpted feel.

Q: Do I need to convert Athleta’s US sizes to UK manually?
A: No. Tellar does this automatically and factors in the garment’s actual fit data—not just the label conversion.

Q: Are Athleta clothes good for curvy or petite frames?
A: Yes, but it depends on the product. Athleta offers Tall, Petite, and Plus ranges—but their UK availability is limited. Tellar can help you find what fits best.

Top Athleta Products Worth Buying

1. Salutation Stash Pocket Tight

High-rise compression leggings with a sculpting waistband. Runs true to size, but Tellar recommends sizing down for a tighter fit if you’re between sizes.

2. Momentum Seamless Bra

Best for low- to mid-impact workouts. Many UK users find this runs small in the band—size up if in doubt.

3. Renew Racerback Tank

Soft, sustainable modal fabric. This one runs slightly large and has a relaxed drape—Tellar typically suggests your normal size or one down.

4. Pranayama Wrap

Ideal post-yoga layering piece. Flowy fit means you can size down unless you prefer a slouchy look.

5. Elation Jogger

Part of the lounge-to-studio range. Slim fit but forgiving waist. Stick to your Tellar-recommended size for a tailored fit.

Why Athleta’s Fit Can Feel Inconsistent

Athleta uses a range of performance materials—PowerVita™, Salutex™, and Featherweight Stretch. Each has different elasticity and recovery, which affects sizing. On top of that, the brand offers:

Talls
Petites
Regular
Plus sizes (up to 3X)

But UK stockists may only carry regular sizes, so knowing your true fit in centimetres or inches makes all the difference.

Real UK Customer Example

“I usually wear a UK 12 in Sweaty Betty but was completely lost trying to buy Athleta leggings online. Tellar showed me that I needed a US 8 for most tights, but a US 6 for joggers. Spot on.”
— Hannah, Cardiff

“Sports bras are always hit-or-miss for me. Tellar told me to size up in the Momentum Bra, and I’m glad I did. Fits perfectly now.”
— Leah, Edinburgh

Avoid US to UK Size Conversion Mistakes

Athleta’s product listings often show US sizing only, which confuses UK buyers. For example:

US Size	UK Equivalent	Notes
4	UK 8	Fitted pieces may run small
6	UK 10	Most leggings true to size
8	UK 12	Sports bras may feel snug

Tellar eliminates this step and provides size guidance based on fit tendencies per product.
