High Sport is fast becoming one of the fashion world’s most talked-about labels. Known for its sculpting stretch-knit trousers, tailored silhouettes, and refined minimalism, the brand sits at the intersection of luxury and performance. But as with many contemporary labels, High Sport sizing isn’t always straightforward—especially when shopping online.

In this guide, we’ll help you:

  • Understand how High Sport sizing works

  • Discover what pieces are worth the investment

  • Get matched to your perfect size using Tellar.co.uk—the UK’s leading free sizing tool

Why High Sport Has Cult Status

Founded by designer Alissa Zachary, High Sport has gained a loyal following for its precision-cut styles and signature kick-flare trousers. The appeal lies in:

  • Uncompromising comfort: Technical fabrics blend with a tailored aesthetic

  • Impeccable craftsmanship: Made in Italy, designed in California

  • Flattering fits: Especially for those seeking wardrobe staples that sculpt without restricting

Celebrities and editors alike are turning to High Sport for elevated essentials that work from day to night.

The Challenge: High Sport Sizing Can Be Inconsistent

Despite the brand’s technical background, High Sport’s sizing can feel inconsistent across different pieces. For example:

  • The Kick Pant runs snug due to its compression-knit structure

  • The Racer Tank has more give, but still favours a fitted look

  • Tops and jackets can vary depending on stretch factor and tailoring

Many shoppers are left asking:

“Should I size up in the trousers?”

“Is a High Sport Medium the same as a UK 12?”

“Will the waistband roll down if I buy the wrong size?”

That’s exactly where Tellar.co.uk comes in.

What Is Worth Buying from High Sport?

Not every piece is created equal when it comes to versatility, comfort, or value. Here's what we think is worth your money:

1. The Kick Pant – High Sport’s Hero Product

  • Fit: Sculpting, cropped, kick-flare

  • Best for: Everyday wear, travel, work

  • Size tip: Most users on Tellar.co.uk need to size up one if they prefer a less compressive feel

These pants have become a fashion editor favourite for a reason—they’re flattering, stretchy, and wrinkle-resistant.

2. The Short Sleeve Top – Understated Essential

  • Fit: Fitted and body-hugging

  • Best for: Layering under jackets or wearing solo

  • Size tip: Stay true to size for a sleek silhouette

Minimal but elevated, this top bridges comfort and polish perfectly.

3. The Racer Tank – Sculpted Summer Staple

  • Fit: Athletic, with full shoulder coverage

  • Best for: Everyday basics

  • Size tip: Slim cut—size up if in between

Made from the same technical knit as the trousers, this tank flatters the upper body while holding its shape.

4. The Knit Blazer – Soft Structure

  • Fit: Tailored but stretchy

  • Best for: Boardroom to dinner

  • Size tip: True to size if wearing open; size up to layer over thicker items

Combining structure and comfort, this is ideal for those who dislike traditional stiff blazers.
