10days Slim Long Sleeve Tee Steel Blue

A fitted long-sleeve tee in that hard-to-name slate blue-grey that somehow goes with everything. The GOTS-certified organic cotton gives it a soft drape and a comfortable feel from the very first wear — nothing to break in, nothing to adjust to.

10days is a Dutch brand with a clear purpose: basics with character, pieces made to last, with that clean Northern European aesthetic that doesn't shout but never goes unnoticed. The tone-on-tone embroidered logo on the chest is the kind of detail you only see up close — the one that quietly sets the piece apart.

Wear it under a blazer on a Monday, with wide-leg trousers on a Sunday, or on its own at home when it's cold but not quite cold enough for a jumper. The piece that always ends up in your bag when you're not sure what to pack.
