Well, slinkier than I usually wear anyway... it's full length and bias cut (have a posh do to go to with my parents) and my bump has just started to expand on a daily basis (am 18.5 weeks). Just a bit self-conscious not of bump but of bumpy bits around it! (hips, mostly) which have got a bit jigglier recently. I don't want to squish myself into Spanx or anything silly like that but is there any option for smooth-line over-or-under-bump knickers to wear under a slim-fitting silky dress?
