I've only been fitted once at Woman's Work but thought they were great. I would definitely avoid bigger stores like Motherhood, though. Their quality has never been great.
If you can't make it in to Woman's Work, I'd suggest searching for an online store in your area (I am sure I came across some recently while looking for Thirsties diaper covers), who may have nursing bras and an in-home location you could go to. They may not be as experienced as Woman's Work, but it might be good enough. Alternately, Bravado has some bras that have a very wide range of sizing (The Body Silk collection, I think it is), that I have liked. If you have some basic info that might work.
Still, going in and having a real bra fitting can be quite the treat! Congrats to your friend, and kudos to you for being so thoughtful!
