Wa'alaikum Assalam
There are women who gain confidence wearing the craziest of things only because a magazine or a tv show tells them it's what's "hot" and "trendy." You will be wearing a garment solely for the sake of Allah during a time where hijaab is not the norm and your rank will be higher than even the women of jannah. Allah takes care of the slaves that put Him first. Yes, people will stare, they'll ask questions, they'll make you feel like an outcast, but you'll also have people who are supporting, who will want to know more about you and your religion, who will comment on how beautiful you look and they respect you for your modesty; but you have to be strong enough not to be affected by people's opinion of you whether it is positive or negative. If you take in the negative comments you will feel miserable; and if you take in the positive comments you may become too prideful to keep improving your deen. Therefore, you have to know yourself and find your identity in a world that wants you to be the same as everyone else and improve on being the best version of yourself. If someone becomes very ill, he won't care about how his Dr's appearance. In a similar way, people that matter will look at what is beyond your appearance. As long as you're clean, kind, and know what you're doing, don't worry about what others will think of you.
