I wear sports bra most of the times,they provides good support,shape,comfort and they are good fashion accessory as well. i also use them as camisoles.
Being a woman with quite large chesticles, I prefer to wear sports bra's over any other kind of bra. I find those "flashy" bra's incredibly uncomfortable, I would rather go without a bra than to wear something that is uncomfortable. (:
I wear an armored bra the rest of the time. There's a small device embedded in one of the cups that summons a battle robot.
