A sectional bra system and accessories includes bra and related jewelry components that can be interconnected in various ways. Jewelry items, such as bra straps, back bands, bridge, and other items, may be formed at least in part from alternating flexible chain segments and rigid connector segments with fasteners configured to attach to standard bra loops. Bra cups for sectional bras include various arrangements of standard bra loops allowing attachment of one or more bra straps, one or more back bands, a bridge, and alternatively other decorative items. Such bra cups may include standard bra loops along all edges. Coordinating jewelry may be made out of the same or similar types of components.
