Introducing a limited batch of Alex Mill Jr. Because everything looks good mini. Details we love: Hidden adjustable waist, zip closure, garment-dyed and washed for a lived-in look. Favorite fact: Our take on an authentic 1940s military jumpsuit. Fits true to size. Sizes correspond roughly to the child's age: 2 should fit children 2/3 years; 4 should fit children 4/5 years and 6 should fit children 6/7 years old. 98% cotton, 2% elastane.
