Genderfluid in need of a good bra.

Hey all, I’m genderfluid (assigned male at birth) and currently leaning femme. I’m looking for a good bra to wear that is discreet and won’t show through my shirt as some people don’t know that I am genderfluid. Can anyone point me in the right direction of a good bra? I don’t mind if it’s wireless or has underwire. Just something that won’t show too much while I’m wearing it under a normal t-shirt. I’m currently wearing bralettes, and I love them, but I’d also like some normal bras to wear as well.

I appreciate any and all help and suggestions!! Thanks in advance!! 🖤🖤

UPDATE: After going out and purchasing a proper tape measure, the calculator put me at 38B/C since I’m AMAB and it couldn’t properly calculate. So I’m assuming that means either 38B or 38C? I’ll def try both. Any style recommendations would still be greatly appreciated 🖤
