I don't know of any off-hand, but I'd check out motherwear (they usually advertise on the back cover of Mothering). The clothes are a bit pricey but I got some really nice stuff there 3 years ago.
For weddings, I have done a ball length skirt in some fancy-schmancy fabric (I don't know what it is) & a long, black loose, but tailored tank. The skirt & whatever jewelry I'm wearing dress it up & the tank is loose enough to hike it up to nurse dd.
