Jersey Pajama Pant - Heather Grey

Owners report James Perse's numeric sizing (0=XS up to 5=XXL) runs true to size, with a deliberately relaxed, California-casual cut rather than a slim one.

Reviewers and sizing guides agree the numbered sizing maps predictably to standard sizes and stays consistent across tees, tanks, long sleeves, and sweats — one long-term owner wears the same size 1 across every James Perse product she owns. The caveat owners flag is that the house cut is intentionally roomy: tees and sweats read slightly relaxed at your true size, so people wanting a trim fit sometimes size down, while button-ups and polos can wear looser than the marked size suggests. On the women's side, fitted jersey pieces are the exception — reviewers note the skinny and fitted styles run small, and pants are cut long.

Sizing advice: Take your usual size converted to the number scale (0=XS, 2=M, 3=L); size down only if you want a trim fit in the relaxed tees and sweats, and size up in fitted jersey styles.

Owners consistently praise how James Perse fabrics feel and drape, but durability complaints dominate third-party reviews of the bottoms: customers describe seams failing and holes developing within months of light wear. Several reviewers say that when they reported defects, customer service dismissed the damage as normal wear and tear and offered no remedy. The consensus across review platforms is that the comfort is real but longevity does not match the price.

Strengths

Soft fabrics and a relaxed drape that owners say feel immediately comfortable.

Watch out for

Seam failures and holes reported within months of light wear, paired with customer service that reviewers describe as unwilling to remedy defects.
