Find Your Fit.

Body measurements in inches and centimeters. Take them once, refer back. If you are between sizes, size up for oversized, down for tailored.

Our fit philosophy

OGYN is cut on a relaxed-modern block — slightly oversized in the shoulders, true through the chest, with a clean drop hem. We do not run vanity sizing. The numbers below reflect actual garment measurements, not body-aspirational labels.

Most customers wear their usual streetwear size. If your shoulders are broader than average for your chest, size up. If you want a tailored, closer-to-the-body silhouette, size down one full size.

How to Measure

  • Chest: across the fullest point of your chest, under the arms.
  • Waist: around your natural waistline, above the hip bones.
  • Hip: across the widest part of your hips and seat.
  • Inseam: from your crotch seam down the inner leg.
  • Sleeve: from the center back of your neck to your wrist with arm slightly bent.

If you're between sizes, size up for an oversized fit, size down for a tailored cut.
