Lovely Shoes
Size: 8.5, Color: Nude/Nubuck
These were a gift. I understand they are "slightly" wide at the toes but fit otherwise. The color & heel height were exactly as desired. She felt the traction was also very good. I look forward to seeing her wear them to her son's wedding!

Wedding Guest Shoe
Size: 6.5, Color: Silver/Glitter
True to size. Very true 6.5 in most all of my shoes. I thought the fit was great but after wearing for a little bit they are horrible. The glitter goes down a little too far on the back and rubs the heel. The sides of your toes will hurt after a little bit of wearing them. Super cute shoes and I toughed it out because they looked great but definitely not the most comfortable shoes.
