Product Insights
Tekla's Striped Organic Cotton Poplin Shirt is a B Corp certified (score 91.7) garment sewn in Portugal from 100% organic cotton poplin with extra-long-staple fibers, stonewashed for immediate softness, fluid drape, and muted wrinkles while retaining structure. French seams and mother-of-pearl buttons resist pilling, fading, and fraying; care requires washing inside out and line drying. Women must size down 1–2 sizes for the unisex oversized fit; the white version may be sheer in bright light, so layering is recommended. Most comfortable in spring and summer but can be layered for cooler months. At $310 CAD—over four times an Organic Basics poplin set—it offers a timeless, function-first design inspired by modernist architecture and sailing ethos, balancing longevity and sustainability with a transparent acknowledgment of its environmental conflict.

Why this is supported
The shirt uses French seams, a dress-shirt construction technique. As noted:
French seams encase every raw edge inside the shirt, so there are no exposed threads to fray after repeated laundering — this is the same seam finish used in fine dress shirts and means the inside of the garment feels smooth against the shoulders and torso, adding a layer of comfort that cheaper overlocked seams can’t match.
