I didn't want to wear one and be branded either, but I have got so sick of people not offering me a seat, it has helped me. So it benefits me, in giving me some more of my my pre-pregnancy confidence back to ask ( that went and was replaced by weariness). I do think it also makes it easier for others to identify you quickly, making it easier for them to offer you a seat. Up to you of course, but if you're in pain or bump is bundled up under a coat, it is useful. I was also pondering this evening that it makes it much more obvious why I am slow, queuing to stand on the right and ought not to be bumped or bustled and I haven't been while wearing it.
