Cropped rib tops use a range of constructions: built-in shelf bras, removable padding, lightly lined or removable cups, full lining, partial lining, and some listings that specify no cup.
Common options include scoop necks, crew necks, round necks, and racerback styles. One athletic tank specifically combines a scoop neckline with a racerback.
Fabric constructions listed include standard ribbed knits, 2 x 2 rib, drop-needle knit, and seamless midweight knit constructions across different cropped pieces.
Several cropped pieces are described as opaque and include full or partial lining for added coverage. Some seamless, fitted athletic tanks rely on a built-in shelf bra for support instead of additional lining.
Tops are generally pullover styles. The lounge pant uses a full elastic waistband; one cropped tank notes a quarter-length button closure, and some pieces list buttons and full lining.
