Lansbury is a modern take on the classic trench coat, with timeless details and a relaxed silhouette that makes it easy to layer. The slightly A-line cut creates room through the body, while the double-breasted front and adjustable belt let you define the waist when you want a more shaped look.

Traditional trench coat details give Lansbury its familiar character. A two-piece collar, button-front closure, and back storm flap bring classic structure, while raglan sleeves with shoulder darts create a comfortable fit through the shoulders. Oversized welt pockets add a practical touch, and sleeve tabs give a tailored finish.

Designed as an unlined coat, Lansbury features deep hems at the sleeves and body for a clean finish. A center-back vent below the hip adds ease of movement, while the matching belt and belt loops complete the silhouette.

Lansbury is a great opportunity to play with the balance between classic and contemporary. Choose traditional trench coat fabric in a neutral shade for a timeless wardrobe layer, or explore unexpected colors and textures to give the familiar silhouette a fresh perspective. Its clean lines work just as well with everyday denim as they do with tailored trousers, dresses, and skirts.

Fabric and Fit

Lansbury is designed for medium- to heavyweight fabrics with enough body to support its relaxed shape and classic trench coat details. Canvas, duck cloth, twill, denim, and coating fabrics are all good options. A crisp, structured fabric will emphasize the coat's clean lines, while a softer fabric will create a more relaxed drape. Consider the weight and stiffness of your fabric when choosing a material, especially if you want to achieve a traditional trench coat look.

Because Lansbury is unlined, pay attention to the wrong side of your fabric and choose a material that will look neat inside the coat.

Fitting Tips

Lansbury has a relaxed fit designed to accommodate layers underneath, so consider how you plan to wear the coat when choosing your size. Check your bust, waist, and hip measurements against the size chart, and think about the amount of ease you prefer in an outer layer.

Sleeve and body length are useful adjustments to consider before cutting your fabric. As Chloe's adjustments demonstrate, you can make separate length changes above and below the waist to fine-tune the overall proportions. If you're between sizes or want to customize the fit, blending sizes can help you achieve a more custom fit.
