A garment hem adjustment system and method, comprising a plurality of fasteners mounted on a surface of a garment proximal to the hem of the garment. The fasteners are aligned in a first column along an inseam of the garment and in a second column along an outseam of the garment. The fasteners are spaced apart a predetermined distance corresponding to a desired adjustment of the garment hem. The lowermost fastener in the first and second columns is adapted to releasably connect to the remaining fasteners in the column. Means are provided for preventing the garment hem from sagging between the columns of fasteners when the lowermost fastener in each column is releasably connected to another fastener in the column.
