STYLETHREAD -- LET'S TALK SHOP!

I'm in a wedding in November and we've been told to wear black shoes.  The dresses are a dark green and hit the floor, therefore they won't be seen.  The bride thought everyone would have a pair in the closet and this would save money.  However, the only black ones I own have pointed toes and I would really prefer a round toe.  The dresses are a heavier satin material.  Please post and suggestions! Thanks!
