It's from a co-op catalog, around the 4000 yen range. Although it's still hot, it's the season when it can suddenly get cold. These are thin, fleece-lined pants. They're stretchy and comfortable to wear. There are pockets on both sides in the front. I've measured the inseam and length, but it's just an estimate. My mother might have altered the size by sewing them. I can't tell without looking closely, but it looks like there might be some stitching... I'm not sure if that's how they originally were. They're a 3L, but since you'll be wearing inner layers in the fall and winter, a size LL might be a bit tight... (just my opinion). For the above reasons, they are new and unused, but the price has been significantly reduced.
