Loved these!  I could wear my regular pants unbuttoned and they fit like a charm.  Then I could wear maternity pants when regular ones got too tight and maternity wear too big (that awkward stage), the bella band kept them up and in place.  Also kept my tummy from being too exposed or getting cold.  I would recommend to anyone.  I gave mine to a friend and she loved them too.  I didn't get a chance to use post baby (because I gave them away), but I would imagine they would work great after you have the baby to be able to keep your pants comfortable as well.
