Are the shirts unisex?

Yes - all Arla Wave shirts are designed to be worn by whoever loves them. Each style has a different cut and fit, so please check the Size Guide before ordering to understand the design differences and find your preferred fit.
How should I care for my shirt?

Follow the care label attached to your garment. To help protect the print, wash it inside out with similar colours and avoid ironing directly over the artwork.

Can I exchange my shirt for another size?

Which size should I order?

We recommend comparing the measurements in our Size Guide with a shirt you already own.

Choose your usual size for the intended exaggerated oversized fit, or size down for a slightly less oversized look. The body length changes only slightly between sizes, while the shirt remains deliberately wide with extra-long sleeves. Please compare the garment measurements with a shirt you already own before ordering, especially if you are petite.
