Maggie "Monica," "Celeste,&quo

Hi all,
I am looking for Maggie Dresses, syle "Monica" or "Celeste" preferably in size 14 (maybe 16). However, even if you don`t have these sizes, could you share your experiences wearing these dresses? I am especially interested to know if people thought the Monica looked "stiff" in photos because it is made of satin rather than organza or chiffon. Also, I am having an early july wedding and wonder if anyone thought the dress was too hot? I ask because when we took pics in the bridal salon, the dress looked very stiff and awkward compared to the organza casablanca gown I tried on, but in the mirror, the dress looked great. If anyone has pics, please let me know! Thanks!!
