Size Guide
Every Jamroc Dept. piece is cut to a premium standard: structured, relaxed, and made to carry the story with presence. The tables below are built from the actual supplier size charts printed on our product pages, so the numbers match the garments we ship. Because our pieces come from more than one maker, cuts vary slightly from style to style. The size chart on each product page is the exact chart for that piece, and it governs if there is ever a difference.
How to measure
Unless a table says Body Measurements, every number here is a garment measurement taken with the piece laid flat.
Chest (flat): lay the garment flat and measure straight across, from armpit to armpit.
Chest (full): the flat chest doubled, the full way around the garment.
Length: from the highest point of the shoulder straight down to the hem.
Waist (flat): waistband laid flat across, not stretched. The full waist is the flat number doubled.
Shoulder: seam to seam across the back. Sleeve: from the shoulder seam to the end of the cuff.
Heavyweight Tees
