Q.I bought the same size as last time, but it's big/small.
A.All socks go through the steam ironing process, which is the last process after knitting.
Bonne maison is slightly more affected by the pressure of steam and the climate (temperature/humidity) at setting, especially due to the complex patterns of various threads.
Due to the nature of the round piece, the size when unfolded may vary slightly depending on the season/design,
It's made in the same size, so please don't worry and wear it.
