Even bras with no underwire, known as soft cup or wire-free bras, can support and create a great shape. This can be accomplished with molded cups. Soft-cup molded bras have cups that are machine-molded from a single piece of material to create cups with no seams and with some shaping for a natural look.
A wireless molded bra will offer some support while still being comfortable. They're available in almost any style, including sports bras, full-coverage bras, wireless bras even bralets. Because they're so smooth, soft cup molded bras are perfect under clingy knits and tees.
