I followed the reviews at the time and bought them in black size 7, I normally take size 6. I have wide feet with a high instep. They stretched very quickly and several times, this caused me to turn my foot over when walking, so I would advise persevering with your usual size or getting a shoe repairer to stretch them for you.
Anyway, after 1 year of frequent wear, they are still my favourite shoes, comfortable, cute looking and very versatile. As somebody has already said, they look especially good with slim/skinny jeans, but they also look good with maxi's and A line knee length skirts. I wore mine through the winter with opaque tights. They looked really good with a short kilt. The crepe sole has worn really well, the only problem is the stiching coming unfastened.
I walk for miles in them and never have to worry about being able to both look reasonably well dressed, but also able to go for a hike if necessary. These and a pair of flip flops are all you need for a holiday suitcase.
I would say, get them at the best price that you can.
