SHOP THE PRINT
GROOVY BLOOMS. Cosmos is for the colour lover who also happens to have excellent taste in vintage. A retro-digital print that nods to 1970s florals while feeling completely, unmistakably now, Cosmos features bold, oversized flowers in soft pink and lilac bursts across deep khaki. The palette is earthy and joyful at once: warm khaki and tan anchor a print that pops with pink, orange and that particular shade of olive that goes with absolutely everything.
The Cosmos collection is crafted in 100% cotton, lightweight and breathable for warm days and easy living. Wear the Cosmos Shirt and Pant together as a head-to-toe statement, or break it up with white, navy or your favourite denim.
Wear the print with...
The cut of this shirt is super comfy - not too long, not too short.
The sleeves can also be lengthened to the elbow, or buttoned up for a shorter sleeve.
And the colours are so fresh and fun.
True to size.
