Effortless everyday layering with a relaxed striped button-up
Wear this long-sleeve, relaxed-fit button-up when you want an easy everyday shirt with a loose silhouette and a straight hem that sits well untucked. Its narrow vertical stripes in light blue and white run across the body and sleeves, with the yoke and fold-down collar turning the stripes horizontal for a classic patterned touch. Smooth, lightweight woven fabric with white buttons and barrel cuffs keeps it a natural choice for casual wear.[1,2]
Untucked Layered Styling
In the brand's styled imagery, this long-sleeve poplin shirt is worn loose and untucked at the sides, with a blue knit sweater tied around the waist partially covering the lower front — a casual, layered look for relaxed everyday wear.[1]
Product comparison
Compared within this brand.
| Pyjama-Stripe Poplin Shirt Relaxed Fit: Choose this if you want a relaxed-fit, long-sleeve button-up in a pyjama-style stripe, made of 100% cotton poplin with a smooth, lightweight feel. It features narrow vertical light blue and white stripes, a pointed fold-down collar, barrel cuffs, and a straight hem that suits wearing untucked. It is listed in a blue colorway in sizes Small through XX-Large; note that the described fit is based on how the shirt appears worn, not measured specifications.[1,2,3,4] | Lightweight Nautical Stripe Shirt Regular Fit: Choose this if you want a short-sleeve, camp-collar striped shirt in a regular fit that offers a looser design around the arms and chest for comfort and movement and suits most body shapes. Made of 100% Liva Reviva by Birla Cellulose viscose, it has a lightweight, soft drape with vertical tan/beige and white stripes that run continuously across the body and sleeves. Note that it is only listed in the Light Brown colour and in sizes medium through xx-large, and a relaxed, fluid drape is best for warm-weather wear rather than a structured look.[5,6,7,8,9] | Small Check Shirt: Choose this if you want a relaxed, boxy short-sleeve button-up in a subtle small check, made of 100 percent cotton with a lightweight woven drape, a spread collar, chest patch pocket, and a straight hem with small side slits. It suits casual styling, including layered open over a tee as shown in the brand's images. Note that sizing runs limited to Medium and X-Large, so it may not work if you need other sizes.[10,11,12,13] |
