I will attempt to give my own little review, but please keep in mind that 1) I have only worn these four times thus far (albeit all four times I wore them all day long). 2) I have extremely narrow feet. 3) This is only based on my own experience! I will break this down into three parts:
Ok, so I think sizing is a definite issue for many. Overall, I would say that these run small. To be on the safe side, I would order a half size up. I am a size 6 1/2, but can sometimes bump up to a 7 depending on the brand or style of the shoe. However, after much contemplation, I purchased my usual 6 1/2 and I have no regrets. I tried both the 6 1/2 and 7 on at the Tory Burch store. At first try, the 6 1/2 felt a bit too snug in the toe, but the heel felt perfect. I was curious to see if the 7 would provide more toe space, and it did. However, the heels were way too large and loose. When I took a few steps, the back of the heels kept falling down due to the ruching. I personally would rather have some very slight discomfort in the toe and have the possibility of some stretching than to have a shoe that is constantly feeling as if it's going to fall off my feet and magically turn into flip-flops ;) Again, I have very narrow feet and small toes. Someone with wider feet may or may not have this same problem choosing between sizes.
Overall, I can attest that the Revas are preeeetty comfortable, Sort of. Kind of. Not like my Gap flats (which are by far the most comfortable flats I own) but still comfy enough to get through an eight-hour day. I'm still getting used to them. They definitely mold to my feet, thanks to the softness of the leather and the heel detailing I have mentioned. I do hope they stretch out a little because they are still tight. I am actually thinking of taking them to Nordstrom to have them stretched. I also wish that the soles were slightly more padded, but I'm sure if it really becomes a problem I can stick some squishy gel inserts into them. I rate comfort at about an 8. In case anyone is interested, here are the dreamy Gap Flats that I could walk all day in: Link: Studded Bow Ballet Flats On Sale!
Lastly, Cost Per Wear/ Appearance Factor:
I really do recommend the Revas, despite the fact they take some breaking in. If you are going to invest in a flat, it may as well be designed by Tory Burch because the woman knows what she's doing! The Revas (named affectionately after her own mother) are chic, timeless, and polished looking. I love staring down at my happy feet and seeing the shiny signature TB emblem. They undoubtedly go with every outfit, no matter what you are wearing. I can only speak for myself, but this was a smart purchase that will (hopefully) last for years to come.
