Frequently Asked Questions

What is the most accurate way to find my hoodie size online?

Take your favorite, best-fitting hoodie from your closet, lay it flat on a table, measure the pit-to-pit chest width in inches, and match that exact number against the brand’s flat garment size chart.

How much shrinkage should I factor into cotton hoodie measurements?

Unwashed 100% cotton fleece typically shrinks 3% to 5% in width and up to 7% in torso length upon first washing. Blends with 20%+ polyester shrink less than 2%.

What does a ‘boxy fit’ mean in hoodie sizing?

A boxy fit hoodie features a wider chest pit-to-pit measurement combined with a slightly shortened torso length and dropped shoulder seams, creating a squared, relaxed streetwear silhouette.
