I wouldnt propose.... but i would show interest in that brother. either telling his sister, or getting my father to talk to his family. i would never approach a man and propose. its allowed in Islam. But men these days are nto liek those of the passed. Where they chershed women and loved them. Now men are too picky... so its risky for a girl to ask.
Nothing wrong with showing interest thats just as good... at least it makes your intentions clear to the brother so he can act upon that then. If a girl did that then she is very brave and also i wouldnt blame her... muslim men hae become lazy in proposing, so women sometiems have to take it iinto thier own hands.
