Can I choose the same bottom size I used to wear?

Even if the size label written on the outside is the same, the standard has changed. Starting in 2025, the size notation system for bottom products has been completely reorganized^[1].

Even if a specific size of a previous product fit you well, you must choose one size larger in newly released bottoms to wear them with a fit similar to before^[2]. This is not because the actual measurements of the patterns being produced have become larger, but because the standards for the indicated size labels have been realigned.

hmmm, rather than choosing based solely on the size label you are accustomed to, choosing one size larger serves as a criterion to reduce mistakes.
