Product Insights & Style Tips
The Alva Long-Sleeve Oversized Poplin Shirt from SIR channels cool, city-ready energy with a laid-back ease. Cut in a relaxed boxy silhouette, it’s woven from breathable striped cotton poplin that feels light and crisp against the skin. The spread collar stays sharp, while dropped shoulders and long sleeves keep the look relaxed. A back selftie at the waist introduces subtle shaping and movement, and the shirt falls about 29 inches from shoulder to hem for a versatile length.
Wear it loose over high-rise denim or slip it into tailored bottoms for a pulled-together moment. The boxy cut skims the torso without clinging, and the back tie lets you tailor the shape at the waist as you move through the day. Button cuffs offer a neat finish and the airy cotton poplin layers easily under blazers or lightweight outerwear, taking you from desk to dinner with polish and ease.
SIR continues its modern spin on classic shirting with this Alva piece, riffing on crisp stripe and effortless comfort. It pairs with everything from slouchy trousers to a satin skirt, embodying the label’s cool, no-fuss attitude and the season’s love of elevated, practical staples.
