A garment comprises an outer shell (12) and a support unit (14) integrally secured thereto by an adjustable securement (16) to allow an upper band (18) of the support unit to expand and contract about a wearer of the garment relatively freely of the waistband (22) of the outer shell so as to avoid collapsing it. The outer shell garment may thus be presented as a tailored, smooth finished garment with no indication that the support unit (14) is beneath and the need to use a stretch fabric in the outer shell waistband (22) is thereby alleviated, facilitating the look of a high quality tailored piece of clothing having a smooth, non-gathered waistband. Integration of the support unit (14) into the outer shell (12) also allows a closure and one or more stays of the support unit (14) to be properly aligned or offset from the outer shell (12) as needed to minimize or prevent bulges or lines in the outer shell (12).
