From Middle English becomen, bicumen, from Old English becuman (“to come, approach, arrive, enter, meet with, fall in with; happen, befall; befit”), from Proto-Germanic *bikwemaną (“to come around, come about, come across, come by”), equivalent to be- (“about, around”) +‎ come. Cognate with Scots becum (“to come, arrive, reach a destination”), North Frisian bekommen, bykommen (“to come by, obtain, receive”), West Frisian bikomme (“to come by, obtain, receive”), Dutch bekomen (“to come by, obtain, receive”), German bekommen (“to get, receive, obtain”), Swedish bekomma (“to receive, concern”), Gothic [script?] (bikwiman, “to come upon one, befall”). Sense of "befit, suit" due to influence from Middle English cweme, icweme, see queem. [script?]
