Pumping at work

For moms who pump at work do you wear a nursing bra, a hands free pumping bra, a regular bra, or some combination of them? I start my new job on Monday and I have no idea what I'm doing. I haven't had to pump much since I've been home with my little one for 5.5 months so I need some advice. I know that I don't respond super well to a pump so has anyone that couldn't pump much still been able to produce enough to breastfeed when you get home? I really want to at least make it to 6 months (he'll be 6 months on the 21st) so I'm hoping it'll work at least until then. Any advice would be very much appreciated.
