Product Insights
Le 31's Pyjama-Striped Shirt in boxy fit offers a roomy square silhouette with dropped shoulders and hip-length hem, constructed as a no-button pullover to distance from actual pajama wear. Made from a lightweight stretch-poplin blend of 64% organic cotton, 34% polyamide, and 2% spandex (90–130 g/m²), the shirt stays crisp and shape-retentive through washes. It is part of a coordinated loungewear set with matching shorts featuring a 4-inch inseam, hidden side-seam pockets, and hook-and-eye waist with elastic back, but the main tradeoff is that breaking up the set with solid chinos or dark wash jeans avoids a pajama look. Priced at $69 CAD (often $49.95 on sale, about 60% less than premium organic cotton shirts with added stretch), it layers well under a blazer or sweater and pairs with brown leather shoes or white sneakers. The pyjama-stripe motif recurs across Le 31's seasonal collection from Simons' in-house label, which also sells $150 tuxedo shirts, underscoring the brand's value proposition.
