The Target Sport Nursing Bra is ok, but there is better. The sides of the bra tend to bow out, like there is too much fabric, and this is noticeable under shirts. A friend gave me some Bravado bras, and I'm in love.
The Target maternity panties aren't much fun either - the briefs go up very high, higher than the waistbands of all my pants. I haven't been brave enough to try out their thongs, so I don't know about them, but they're cute.
