If you only buy one piece from the drop, let it be the literal heart of the Sundae School uniform. We took that 70s/80s gyobok (Korean school uniform) lore and turned it into the ultimate "Honor Roller" flex. This is our actual staff uniform at the Hester Street flagship. 

It’s the perfect high-low cheat code: structured enough to look expensive, but bio-washed so it feels like that one vintage find you never want to take off. The cropped fit hits exactly where it should, and the mochi-quilted collar adds just enough flair to keep them guessing. Formal enough to look sharp, chill enough to wear to the function.
