The waist size of them was 30 inches that is a little bit large for me.
I have worn the trousers in size of 28 inches since I was a high school student.
However I'm getting fat recently. My waist size has been increasing.
I changed the size of the trousers for the first time.
I regret the shopping.
I should have bought them in size of 28 inches.
I should try to fit my body to them by diet & exercise.
