This grey Acne Studios Janny double-breasted checked blazer is cut for a relaxed fit and shaped with notch lapels, a front button fastening, long sleeves with buttoned cuffs, side pockets and a back central vent. Acne Studios makes a strong case for power dressing at every opportunity. And conveniently, we don't particularly want to take this blazer off either - even when it's time to sleep.
