Wedding party attire help?

So my wedding was supposed to be a casual wedding and outside. My brides maids got casual sundresses before My fianc�es groomsmen decided they all wanted to wear a tux. Is it going to look stupid that the guys are wearing tuxs and brides maids wearing casual dresses. Or should my brides maids get new dresses. It just feels like it will look unbalanced and His friends are going to look the best atthe wedding. I also have a short wedding dress but I am glaming it up with nice hair and jewelry and shoes and stuff.
