  • Publication number: 20130183885
    Abstract: The present invention provides a garment with cup sections, which prevents the occurrence of slippage due to an action of a wearer or the like and thus can maintain the wearer's bust silhouette fine without any effort of correcting the slippage when it is worn. The garment with cup sections according to the present invention includes: a pair of cup sections (101) and a back cloth(s) (103). The back cloth (103) is arranged on the lateral sides of the cup sections (101). Each of the cup sections (101) includes a stretchable member(s) (101a) and a linear or strip-shaped interlining member(s) (105). At least one end of the interlining member (105) is on a verge's line-corresponding portion in the cup section (101), and the stretchable member (101a) is arranged in a region between the interlining member (105) and the lower edge of the cup section (101).
