[About bag stitching]
All surfaces that come into contact with the skin are covered with bag stitches.
Bag stitching refers to sewing once outside the finished line and then hiding the sewn part in a bag to create a seam allowance.
By hiding it in a bag-like shape, the seam allowance does not touch the skin.
The photo below was taken of the armpit, the side that touches the skin.

[About waist elastic]
We have adopted ``BB waffle elastic'' for the waist elastic, which is a concern for tightening.
"BB waffle rubber" is difficult to bend or turn over,
Made of a softer material that stretches better than regular rubber.

About laundry

Place it in a net and use a neutral detergent (such as Emar) that does not contain fluorescent agents.

Although it is possible to use a weak alkaline detergent (such as Attack), we recommend using a neutral detergent that does not contain fluorescent agents to prevent color fading and ensure long-lasting wear.

Please avoid using a dryer at home or in a coin laundry. This will cause it to shrink.

Gently tap the entire surface with your palm to smooth out any wrinkles, then dry in the shade.
