Military training will issue military uniforms. How to change pants into straight pants under the condition of insufficient tools, that is, stovepipe pants? The following is what our classmates changed in military training, I think. Usually, it's best to find a pair of pants that suit you, and don't choose tights that need human body stretching, because military training pants are not elastic, and inelastic stovepipe pants are the most suitable size. Borrow what others can wear, and find a tailor to change it according to his pants. If you change it yourself, just turn it over. Draw lines with chalk according to the size and sew it back and forth once or twice according to the general sewing method. Online is really not good.
