Size Guide
All Parallel World apparel is made to order on premium blanks. Measurements below are garment dimensions (not body measurements), sourced from our production partners, so you can compare directly to a piece you already own. Sizing can vary slightly (about 1.5″ / 3.8 cm) between production batches.
How to measure
Length — from the high point of the shoulder (beside the collar) straight down to the hem.
Width / Chest — measured flat, one inch below the armhole, from seam to seam, then doubled for full chest circumference.
Sleeve length — from the center back collar, along the top of the shoulder and sleeve, to the cuff.
