Should I choose the same size I used to wear, or go one size down?
This question seeks to confirm which size to select in order to buy clothes of the same size as before, as the sizing notation method on the official online store has changed.
The actual size of the clothing has not changed, so you should choose one step down in the label size from what you used to wear.
The label notation has gone down by one step, but the actual size of the clothing remains the same as before[1]. As the operating company of the official GRAMICCI online store changed, the sizing standard changed from the ASIA standard to the USA standard[2]. Only the reference standard changed, while the width and length of the clothes did not change[3].
Because the actual measurements are the same, you need to choose a label one size smaller to get the fit you usually enjoyed wearing[4]. If you comfortably wore size M in the past, you should choose size S now, and if you wore size L, you should choose size M[5]. Likewise, if you go down one step each—from the existing size XL to size L, and from size XXL to size XL—you can wear the same size as before[6].
Which size the existing ASIA S size corresponds to currently has not yet been confirmed in official materials.
