I got the lace version in Size B and the fit was as expected according to the chart HOWEVER I found the lace rubbed me when I walked - there is a bit that will naturally rub exposed bits of skin while you are walking and the nubby textured lace surface irritated me. Returned for the plain version, which won't have the problem with annoying nubby lace. Me: 5 ft 6 inches, 140 lbs at 21 weeks pregnant (normally 115 lbs but an illness prior to conception made me gain a lot making my pre-pregnancy weight 130 lbs) - since the beginning of the 2nd trimester, little mounds of extra fat started accumulating on my inner thighs (ugh), that made chafing a problem for the first time.
