Operation method
First, we should spread out our folded shirts flat and straighten the wrinkled part. And all the buttons are buttoned up and the whole shirt is laid flat.
Fold one of the two pomelos in a short section. Fold it along the other sleeve.
Then fold the sleeve back to coincide with the edge here.
Then fold the other one according to the step playing method of the previous sleeve.
Then arrange the sleeves without wrinkles.
Fold the lower part of the shirt to the upper side of the collar. If you think it is too big, you can also fold it into three small parts, which will be smaller.
After all the above steps are completed, the whole shirt will be turned upside down, just like the shirt you just bought.
