Undergarment
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.
1 . An undergarment for a wearer, comprising:
an undergarment body made of elastic fabric, the undergarment body being provided with two cup portions;
a zipper disposed on the undergarment body and positioned between the two cup portions, the zipper when unfastened being configured to open the undergarment body;
side support panels configured to provide lateral lifting force, the side support panels disposed on the undergarment body and positioned at outer peripheries of the cup portions; and
two positioning stays, located on a front of the undergarment body under the cup portion for supporting each one of a wearer's breasts, configured to provide a lower periphery constraint to each cup of the wearer's undergarment to retain each of a wearer's breasts.
2 . The undergarment according to claim 1 , wherein the side support panels are made of elastic fabric, and the side support panels are fixedly attached to an outer surface of the undergarment body.
3 . The undergarment according to claim 2 , wherein the side support panels are glued to the undergarment body.
4 . The undergarment according to claim 2 , wherein upper ends of the side support panels are connected to shoulder straps of the undergarment body: lower ends of the side support panels are connected to a lower edge of the undergarment body; and a lateral side of the lower ends of the side support panels extends to the zipper.
5 . The undergarment according to claim 4 , wherein an edge of the side support panels proximate to the cup portions extends in a curvilinear contour.
6 . The undergarment according to claim 1 , wherein the positioning stays are fixedly attached to an inner surface of the undergarment body, and the positioning stays are positioned within a coverage area of the side support panels on the undergarment body.
7 . The undergarment according to claim 1 , wherein the undergarment body comprises a surface elastic fabric and an inner elastic fabric, the surface elastic fabric and inner elastic fabric being adhesively bonded via an elastic adhesive layer; the elastic adhesive layer comprises a frame portion and lateral binding portions; the frame portion extends along an edge of the undergarment body and comprises an upper elastic edge and a lower elastic edge; upper ends of the lateral binding portions are connected to the upper elastic edge; lower ends of the lateral binding portions are connected to the lower elastic edge; and the lateral binding portions are configured in an inclined orientation with upper ends extending toward an anterior chest region and lower ends extending toward a posterior waist region.
8 . The undergarment according to claim 7 , wherein the elastic adhesive layer further comprises arc-shaped lateral support elastic portions; upper ends of the arc-shaped lateral support elastic portions are connected to the upper elastic edge; lower ends of the arc-shaped lateral support elastic portions are connected to the lower elastic edge; and the arc-shaped lateral support elastic portions are positioned within a coverage area of the side support panels on the undergarment body.
9 . The undergarment according to claim 7 , wherein the elastic adhesive layer further comprises posterior shoulder strap elastic portions; upper ends of the posterior shoulder strap elastic portions are connected to the shoulder straps of the upper elastic edge; and lower ends of the posterior shoulder strap elastic portions are connected to the lower elastic edge.
10 . The undergarment according to claim 1 , further comprising: an inner padding positioned inward of the zipper, a lateral edge of the inner padding being connected to a side of the undergarment body at the zipper.
11 . The undergarment according to claim 10 , further comprising: an adjustment buckle connected to the undergarment body and positioned between the zipper and the inner padding.
12 . The undergarment according to claim 1 , wherein the zipper comprises a slider and two zipper straps, the two zipper straps are respectively connected to the undergarment body, the slider is configured to operate engagement/disengagement of zipper teeth of the two zipper straps, the slider comprises a slider body provided with a through-hole and a Y-shaped channel for passage of the zipper straps, the through-hole is in fluid communication with the Y-shaped channel; a pull tab is provided with a pivot shaft rotationally mounted on the slider body, the pivot shaft is provided with an eccentric protrusion, a locking element is elastically deformable, an end of the locking element is connected to the slider body, an opposite end of the locking element is provided with a locking prong traversing the through-hole, the locking prong is configured to engage/disengage the zipper straps, and the eccentric protrusion pushes against the locking element to induce elastic deformation of the locking element to disengage the locking prong from the zipper straps thereby achieving unlocking upon rotation of the pull tab relative to the slider body to a preset angle.
13 . The undergarment according to claim 12 , wherein the slider body comprises a first wing plate, a second wing plate, and a guide post connecting frontal ends of the first wing plate and the second wing plate to form the Y-shaped channel; the guide post is provided with a slot for insertion and fixed connection of an end of the locking element; the through-hole is disposed on the first wing plate; the first wing plate is further provided with two spaced constraint assemblies for constraining the pivot shaft; the locking element is positioned between the two constraint assemblies; each constraint assembly comprises two constraint prongs spaced apart; the pivot shaft is threaded between the two constraint prongs of each constraint assembly; and upper ends of the two constraint prongs are elastically converged to restrict disengagement of the pivot shaft.
