Familiar Half Pants Blue Check Size 100 cm I purchased these intending to use them for formal wear, but I ended up using different pants, so I didn't wear these and they've been stored at home. The waist has elastic and can be adjusted, so those concerned about the size can rest assured. Please refrain from purchasing if you are sensitive to items that have been stored at home for a long time and have been washed at home. These are not brand new, unused items from a store.
