    I was able to find just the right size.

    I ordered it for winter work expecting thick material, elasticity, and ease of wear.

    It's usually a size 11, so when I ordered size 11, it was pretty big.

    It was big even in size 9, and finally fit in size 7.

    The return was free, but I was hoping you could give me a little more detail on the size chart.

    It was very comfortable to wear.

    The stretchy fabric makes it easy to wear

    Since they are sewn from stretchy fabric, the pants are easy to wear by stretching them from the stage of wearing them. Of course, it's also smooth and comfortable when you take it off. They don't seem to get tired even if you wear them for a long time, so they seem to be useful even when traveling by airplane or train. Also, I was thankful that it didn't wrinkle.

    It's easy to wear

    I think the waist part is elastic so it's easy to wear. I think it's a color where dirt is easily noticeable, so I want them to take out the taupe cardboard knit pants that were there before again.

    Heavy Lotte confirmed

    I've never come across such comfortable underpants! After delivery, my waist circumference didn't return and I didn't like the tightness, so I gave up quite a few pants, but these are extremely comfortable and I can wear them every day. It's both pretty and casual, so I end up wearing it every day. Even if you put thin tights or spats underneath during this cold season, it doesn't feel tight at all. I want them to be developed in black too!

    The silhouette and comfort are the best

    I went to the store to buy a straight skirt, but I bought it unplanned because it was comfortable to wear and had a good silhouette. (I bought a skirt too.) I bought navy, but since the material isn't too casual, I can wear it for business, and I love it both in public and private. Also, I love space materials, and the smooth fabric makes it easy to move around. Also, since it's made larger, it's a good idea to try on something that's one size down on a regular basis. If in doubt, buy it.
