A stretchable fabric sleeve is configured for use as a prosthetic shrinker or as a prosthetic sock and broadly comprises a unitary receptacle broadly including a tubular section and a rounded end section. In particular, the rounded end section includes opposite panels that are knitted in seriatim with a plurality of interlaced short rows that provide a progressive taper from the open margin of the tubular section to the lowermost toe end of the end section. The progressive taper of the knitted panels permits the outermost edge of the rounded end section to assume a rounded shape that comfortably conforms to an amputated limb and is devoid of any sewn seams that would otherwise irritate the sensitive end of the amputated limb.
