Okiale,
From other posts,I can see that you are new the Orthodox world. Ask your Rabbi or mentor for guidance before diving into a white shirt black suit and hat garb. Depending on your progress, it may appropriate to dress differently at first or at all.
(A friend of mine once decided he wanted to be chassidic and bought himself a streimel and bekishe and everything that goes with that. After a few years, the novelty wore off and he went back closer to his sefardi roots. He stills wears the streimel, but told me he doesn’t feel comfortable in it in his local sefardi minyan).
My point is, take small steps and don’t lose the momentum. If you take a big leap at once, you may be more susceptible to trip and fall.
Hatzlacha Rabba!!
