Why Seasalt Cornwall Fit Can Be Tricky
Seasalt is famous for:
Relaxed silhouettes and flowing fabrics
Petite, Regular, and Tall ranges
Sizes UK 6–28 in many styles
Ethically sourced materials like organic cotton and bamboo
Their sizing philosophy favours comfort over cling, which means many styles are generous by design. But that doesn’t mean all pieces fit the same.
Does Seasalt Cornwall Run Big or Small?
In general: Seasalt Cornwall runs true to size, but many styles—especially tunics and jersey dresses—run slightly large due to their relaxed fit.
Dresses
Jersey and linen styles are often roomy around the waist and hips
Empire-line and shift dresses may feel oversized on smaller frames
Fit tip: If you’re between sizes or petite, consider sizing down
Tops & Tunics
Most feature a relaxed or A-line cut
Drop shoulders and wide hems are common
Fit tip: Runs roomy—Tellar adjusts based on your bust/shoulder width
Trousers & Skirts
Many have elasticated or part-elastic waistbands
Wide-leg and straight-leg fits dominate
Fit tip: True to size, but Tellar accounts for waist-to-hip proportion
Coats & Jackets
Cut to allow layering underneath
Often slightly oversized by design
Fit tip: True to size—but Tellar can suggest if a size down will suit your frame
