Locking pull-tabs for a zipper include a first pull-tab that may be connected to a first slider and a second pull-tab that may be connected to a second slider of the zipper. The first pull-tab and second pull-tab include a first locking coupler and a second locking coupler, respectively. The first locking coupler and second locking coupler may enable the first pull-tab and second pull-tab to engage each other in a manner that secures a zipper in a closed arrangement and, thus, provides some security to contents of an item that are enclosed in the item with the zipper. The first locking coupler and second locking coupler may engage each other in a manner that requires intentional and conspicuous manipulation of the first pull-tab and second pull-tab to uncouple them. Methods for locking a zipper are also disclosed.

A slide fastener slider includes: a lower member; an upper member; a cover; and a pull tab. The lower member includes a lower blade, a guide column, an upper plate portion, and an attachment column. The upper member includes a flat plate portion, an opening portion, and a placement portion. The cover includes, at an end portion thereof in the front and rear direction, an engaging portion engaged with an engaged portion provided on the attachment column. A shaft portion provided at one end of the pull tab is disposed in a space formed between the upper plate portion and the cover. The placement portion is sandwiched between the engaging portion of the cover and the upper plate portion by attaching the cover to the attachment column by engaging the engaging portion of the cover with the engaged portion of the attachment column.

The present application discloses an undergarment including: an undergarment body made of elastic fabric; a zipper; side support panels configured to provide lateral lifting force; and positioning stays configured to provide lower periphery constraints. The undergarment body is provided with two cup portions. The zipper is disposed on the undergarment body between the two cup portions, which when unfastened, opens the undergarment body. The side support panels are disposed on the undergarment body at outer peripheries of the cup portions. The positioning stays are arranged on the undergarment body below the cup portions. This undergarment achieves visual slimming of larger bust profiles while maintaining natural contour aesthetics, exhibiting dual applicability for both athletic and daily wear.
