Detailed Houndstooth Fabric Pattern
This blazer is crafted with a dense, small-scale houndstooth check pattern that covers its entire visible surface. The sophisticated geometric pattern offers a classic tailored look for smart casual or professional wear.[3]
A single-breasted houndstooth blazer with dark, polished buttons
Wear this single-breasted, two-button blazer as a polished layer for work or smart-casual occasions. Its dark, glossy-looking buttons contrast with the lighter houndstooth fabric for a refined finish, and it's shown with the top button fastened and the bottom left open.[3,4]
Blazer with a moderate notch lapel that sits flat
This semi-slim houndstooth blazer features a notch lapel of moderate width with visible seam lines, shown lying flat against the chest as worn. The notched collar is also visible from the rear and, on the model pictured, lies flat against the upper back.[3,4]
Layering a blazer over knitwear
This blazer was styled over a turtleneck, with its sleeves ending slightly above the wrist bone so a knit cuff shows underneath. Each sleeve ends with a visible cuff, which keeps the sleeve detail looking finished when layered over a sweater. As seen on the model, the sleeve hems have a straight finish.[3,4]
A tailored back with a single rear vent
This semi-slim houndstooth blazer features a vertical center-back seam that opens into a single rear vent at the hem, with defined shoulder seams visible from behind. In product photos worn by a model, the notched collar is shown lying flat against the upper back. It suits shoppers who want a tailored jacket with classic back construction for dressy or office wear.[3]
Semi-slim blazer with an upper-hip length as worn
This houndstooth virgin wool blazer is cut in a semi-slim fit, and as shown on the model it falls to the upper hip, follows the contours of the back, and has a slight flare at the hem. Shoppers can use this as a reference for how the jacket sits and drapes when worn, noting the image does not indicate the size worn.[3]
Product comparison
Compared within this brand.
| Houndstooth Blazer Virgin Wool Fabric By Moon London Fit - Semi-Slim: Choose this if you want a single-breasted, two-button blazer with a semi-slim London fit that narrows at the waist, cut in 100% virgin wool fabric by Moon that the retailer describes as luxurious British cloth, in a brown small-scale houndstooth check with notched lapels, flap pockets and side vents. It comes in regular sizes 36 through 48, and it requires dry cleaning only, which matters if you prefer low-maintenance care.[1,2,5] | Armoured Horses Neckerchief Imported From Seoul: Choose this if you want a small, versatile square scarf for subtle everyday styling—at about 21 inches by 21 inches (53 cm), reviewers say it works as a neck scarf with a jeans jacket or tied onto a handbag without overpowering an outfit. Its repeating armoured-horse motif on a cream-beige base earned praise for adding visual interest while staying understated, and the fluid, lightweight 100% polyester weave has a smooth, silk-like look with a soft drape. Note it comes in one size only (in Off White and Blue), and while it looks silk-like, it is fully polyester.[6,7] |
