I am like that too. I'm now full-time but when I started, my first articles were panties. Very discrete and very feminine. After I became comfortable in them, then I started to branch out and add to it. I was too nervous for bras for a while because I was worried about other people noticing the straps. I found they also increased my dysphoria significantly because they would make me feel inadequate, as I didn't have much to fill the cups with. I had to start wearing sports bras due to the sensitivity in my nipples, but I never really became comfortable until I came out to everyone. Now that I'm a woman full-time, it's ok to me if others see the outline of a bra strap. Also, now that my boobs are up to an A cup, I don't feel inadequate, as the cups now have something to hold and protect.
