Women's Brass Plum by Nordstrom high heel sandal

$15.00 for all four pairs. What is the saying, "If you like something, buy one in every color"? I loved these Brass Plum sandals so much I bought them in red, brown, black and pale pink. Satin upper with crystals. The red and black are size 9.5, the pink and brown are size 10, but they all seem to fit the same. The black heel was loved on by a dog some years ago, but it's barely visible.
