What Is the Rails Brand Known For?

Founded in Los Angeles, Rails started with a cult-favourite flannel shirt and has since evolved into a full lifestyle collection. Their aesthetic blends:

• Laid-back luxury

• Easy silhouettes with tailored finishes

• Premium, ultra-soft fabrics (e.g. Tencel, cashmere, linen blends)

• Seasonless appeal—perfect for capsule wardrobes

• Elevated basics with subtle detail (e.g. ruffles, ties, raw hems)

While Rails is loved for its effortless fits, the sizing depends on fabric, silhouette, and how “relaxed” the design really is.

So, Does Rails Run Big or Small?

In general:

• Rails runs true to size in most items, with a slightly relaxed fit across shirts and knitwear

• Fitted dresses and trousers may run small, particularly through the waist and bust

• Shirts and button-downs can feel roomy, especially when sized up for layering

🧵 Fit summary:

• Tops = true to size or slightly relaxed

• Dresses = true to size, but size up if curvier or taller

• Bottoms = can run small in the waist—check with Tellar

🧠 Use Tellar to get your perfect size in Rails based on bust, waist, hips and height.
