Supplemental apparel constriction anchor systems for customized constriction of apparel

A supplemental apparel constriction anchor system suitable for customized constriction of an article of apparel having two sides that overlap for closure of the article of apparel, the system comprising:

• a constriction clasp comprising a reversible locking component fixed to an expansion head of a fabric insertion shaft designed to penetrate through a fabric material of the article of apparel until reaching the expansion head, wherein the fabric insertion shaft is constructed to interlock with a first backing component that holds the fabric insertion shaft in place within the fabric material between the expansion head and the first backing component;
• and
• a constriction anchor comprising an anchor head flange fixed to a second fabric insertion shaft designed to penetrate through the fabric material of the article of apparel until reaching the anchor head flange, wherein the second fabric insertion shaft is constructed to interlock with a second backing component that holds the second fabric insertion shaft in place within the fabric material between the anchor head flange and the second backing component, and wherein the anchor head flange is of sufficient size to reversibly retain the reversible locking component in the locked position,
• wherein one of the constriction clasp or constriction anchor may be positioned on the closure edge of the overlapping side of the article of apparel and the other of the constriction clasp or constriction anchor may be positioned on the underlapped side of the article of apparel to allow customized constriction of the article of apparel by selection of the underlapped side position in relation to the reach of the position of the constriction clasp or constriction anchor on the overlapping side, to reversibly couple the constriction clasp and constriction anchor in locked position for customized constriction of the article of apparel.
