This blue cotton Haider Ackermann crewneck sweatshirt features long sleeves, as well as the obligatory ribbed cuffs and hem. Here at Browns HQ, we're big fans of the comfortable designer statement, and we've found this electric blue jumper does just the trick. Try swapping your morning flat white for a good stare in the mirror while wearing this sweatshirt instead. Trust us, it will give you a good jolt. Catch us sauntering our way into the office in this Haider Ackermann top with M. Cohen, Maison Margiela and Porter-Yoshida & Co.
