The Shirt

THE LONDON CLASSIC — WHITE MUSCLE FIT SHIRT FOR ATHLETES

Introducing The LONDON — a masterfully tailored white shirt engineered for the elite physique. Designed exclusively for bodybuilders and men of exceptional build, this piece redefines what it means to wear luxury with strength.

With a precision aggressive taper, this shirt celebrates the V-tapered form — broad shoulders, commanding chest, and a narrow waist — delivering a silhouette that is both powerful and refined. Every contour has been sculpted to enhance your physique without sacrificing comfort.

Crafted from premium, breathable cotton-blend fabric, the material offers a luxurious drape that flows effortlessly over muscle while maintaining structure. The result? A shirt that feels like it was custom-made, every time you wear it.

Subtly elevated with a discreet, hidden logo, The Sculpted Classic maintains a clean, minimalist aesthetic — making it effortlessly suitable for the office, formal occasions, or refined everyday wear. Understated yet commanding, this shirt transitions seamlessly from boardroom to evening engagements.

What is My Fit?

Diamond Theory has 2 Fits for shirts:

Muscle and Mass

  • Muscle: This fit is designed with Bodybuilders in mind as this has an aggressive taper, bringing it right in at the waist.
  • Mass: This fit is designed with Strongmen in mind as this has a less aggressive taper as Strength Athletes tend to have a thicker core.

Please take this as a reference and refer to the size guide with your measurements.
