The Aerie Size Chart, Interactive

Aerie's chart is compact and young-skewing (A to DDD on 30 to 42) with soft construction that flatters the middle of the grid and runs out of structure at its edges.

Reading it

How Aerie sizing reads

Aerie’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.

Honest edges

Where this chart ends

Past DDD, the honest move is a structure brand: Freya or Panache in UK letters. And if a symptom (riding band, gaping cup, poking wire) sent you size-hunting, the fix guides decode it before you spend anything.
