My experience of maternity clothes is that some cheap tops from H&M are OK, and everything else needs to come from JojoMamanBebe. I need to wear slightly mumsy type clothes to work, cos that's just how my job is, so empire line jersey dresses are ace for that. I have a load that I wear normally, but have just bought 2 new ones from there, that also have breast feeding holes under the wrap top. Boyfriend and I decided 'not too bad, almost decent dresses', which is about as good as I think maternity clothes are going to get. Bought two pairs of trousers from there early on, but only really need to wear them now - and they just don't stay up, crotch around my knees is really uncomfy.
The best things I've bought recently are Next harem pants in black. Go up over the bump, properly elasticated, and look semi 'normal'. I found a pair in navy online to (not maternity), and they are also great. Also have two tunics from Fat Face that are still fitting well (quite flarey under the boobs), and two maxi dresses from Fat Face too - last year and the year before I think, that I reckon will get me near to the end. Yay Fat Face and it's nice bright colours and under boob flareyness!
I move from biker boots (same Fly style in various colours) to Birkenstocks in May, and stay like that if I can until October, so bought two new pairs in pink and red the other day just to cheer me up.
