If you are talking about the judpa, the full outer gown, then this is most advisable. It gives you full covering and full modesty. We women in Islam, do not want any man being able to see our shape of body. It is a form of protection from unwanted glances and attention. It is good for summer and winter, keeps you cool and warm. Allah knows best. This is a mercy from Allah, for women to wear, you will benefit from this "garb". If you are thinking of wearing something less, make sure it is a long dress type, arms covered, and ankles covered, and the chest covered. Always wear your hijab , be it in garb or not, that is, in public.
The garb, is a recognised symbol of clothing for women to wear. As im sure you recognise the men , especially on Jummah, or by the beard. Then again, men are less recognisable if they dont wear their garbs or a beard. So with this, you become recognisable and greeted accordingly as a muslim. Its a wonderful feeling to be seen, and greeted. A good way to make muslim freinds also. I am a revert, If you have any questions, please ask. You can take tiny steps into your transition or go full on. Dont be overwhelmed by all this as regards dress sense, just be modest. Prayer is important, just as modesty is.
