A front-tie top may refer to a bikini top (or less commonly, a bra undergarment such as at Danbooru post #478758) which closes in front of the chest by two or more ends tied together, forming a knot between the breasts. It may also refer to a plain shirt or crop top tied in the same manner, forming a type of halterneck which both emphasizes the resulting bare midriff and the bustline or cleavage. Variations may be purely ornamental in nature rather than functional (e.g. bow bra, Danbooru post #490346), mostly theoretical (a mere ribbon at Danbooru post #652439), or may feature a metal loop to help connect bra cups together and tie to a neck strap.
The term could arguably be used to describe a corset, bustier or other similar garment which features a frontal latticework that, in turn, terminates in a central knot (e.g. Danbooru post #419234).
