How Our Sizing Works

We build sizes by height & weight for a precise, actually slim fit—especially for slim/lean builds with narrow shoulders.


This cuts the guesswork of neck/sleeve combos and reduces excess fabric through the chest and arms.

Niche Fit: Who We're Best For

We’re built for slim/lean frames with narrow shoulders and a clean, close silhouette through the chest and arms.


If most “slim fit” shirts still billow at your midsection or pull only when you size down, our height- & weight-based sizing solves that—off-the-rack, no tailor required.

Who It's Best For

  • Slim/lean builds seeking a truly narrow cut in chest, waist, and sleeves
  • Narrow or sloping shoulders where regular “slim” still looks boxy
  • Straight or tapered torsos (little midsection fullness) wanting a clean line under a blazer
  • Fans of a tailored feel with minimal extra fabric and higher armhole for mobility

Who It's Not Ideal For

  • Broad builds (wide shoulders, developed chest/arms) who prefer ease in the biceps/upper back
  • Fuller midsections or prominent midriff where extra waist room is needed for comfort
  • Relaxed/drapey style preference (you like a roomier, casual silhouette)
