Pair of trousers stretchable around a waist

Abstract

In a pair of trousers stretchable around a waist, to be able to prevent from getting wrinkles and the like on upper parts of a front body and a back body with certainty and improve an appearance so as to make a tuck and an opening end of a storing part unnoticeable and yet, to be able to enhance its productivity. In a pair of suit trousers 1 , by following attachment of a tuck 5 to each of upper ends of side lines LS and RS, a primary elastic material being joined between an elongating part 3 B and a storing part 3 A becomes elastic, thereby being elastic around the waist. With this movement, tucks 5 are opened and closed, therefore, it can prevent from getting wrinkles and the like on upper parts of a front body 4 and a back body 9 . Also, tucks 5 are attached along side lines LS and RS, thereby being united with side lines LS and RS with tucks 5 closed. Even if tucks 5 are opened, tucks 5 are extensions of side lines LS and RS, thereby being unnoticeable. Moreover, an opening end 3 Ab of the storing part is attached along each of side lines LS and RS, thereby being recognized as a line which is an extension of each of side lines LS and RS and furthermore, belt loops 7 are attached thereto, thereby improving the appearance so as not to be noticeable.
