Product Insights
The Coloured-Stripe Poplin Pyjama Short from the Miiyu x Twik collaboration, designed in Canada by Simons, features seasonal Twik-inspired stripes that bring ready-to-wear style to sleepwear at a designer-leaning price, currently on sale at CA$29.95, undercutting premium organic brands by over 30%. The 100% organic cotton poplin starts crisp and softens with each wash, becoming increasingly gentle on sensitive skin while remaining breathable and moisture-wicking, and resists sagging, pilling, and clinging. Its no-drawstring covered elastic waistband is smooth and pressure-free but lacks adjustability, and the organic cotton is not third-party certified (e.g., GOTS). Sizes S, L, XL cover waist 28–36 inches with a 3–3.5 inch inseam; this limited-edition style may not be restocked after the season.
