📐 How to Measure?

If you are unsure between two sizes, always go with the larger one. Here is how we measure our garments:

  • Width (Chest): Measured across the chest, 1 inch below the armhole, when laid flat.
  • Length: Measured from the highest point of the shoulder down to the bottom hem.
  • Sleeve Length: Measured from the center back of the neck, down the shoulder, and down to the wrist.
