Every　woman＇s　breast　shape　is　unique,　so　it　is　hard　to　find　a　ready-made　bra　that　fits　perfectly.　Commercial　software　has　been　claimed　to　simulate　virtual　bra　fit　based　on　adjustable　avatar　size　and　fabric　mechanical　properties.　However,　the　body　was　assumed　to　be　rigid　and　the　bra　materials　were　oversimplified.　Finite　element　modeling　has　been　widely　used　in　product　engineering,　but　its　application　to　bra　design　is　still　in　its　infancy.　The　success　of　a　finite　element　model　of　bra　fitting　requires　a　realistic　body　model　with　the　correct　settings　for　the　material　properties　of　the　thorax,　breasts,　and　skin.　The　breast　boundary　and　its　loading　condition　should　be　specifically　defined.　The　types　of　mesh,　elements,　and　the　pretension　of　the　bra　components　need　to　be　systematically　researched　to　make　the　bra-body　contact　model　run　successfully　to　predict　bra　displacement,　stress,　and　force　distribution.　This　chapter　provides　a　critical　review　of　previous　research　and　introduces　new　methods　to　create　more　realistic　finite　element　modeling　of　bra　fitting.　©　2016　Elsevier　Ltd　All　rights　reserved.
