These pants fit meeeh.. OK... I am about 53/54 current pregnancy weight is 155 (I normally wear size 5 pants so I bought a medium) the length is a little long so the bottom of the pants always touch the ground and the crotch area is a little too roomy. The band bends when I bend so I always have to fix it and its getting tight. Im only 6 months pregnant and Im aftaid they won't fit me once Im further along BUT I think if I had gone with a size up the pants would have been too big. There is a sizing band in these pants so you can adjust them if they are too big but nothing can be done if they are too small.
