Thanks to all of you for responding to my thread! Angie/Carter/Banoffi/Robin/JAileen per your advice I called Nordstrom. I talked to Mary, who gladly exchanged the booties for a size 7. I didn't even need to give her credit card info. I hope they work. Sometimes a half size up is perfect, sometimes it just doesn't fit anymore, we'll see.
Jeanie -- it looks like we have the same type of feet. I will continue to try wide widths but as of yet have not found a size W shoe that works. European shoes usually fit me best, as they are cut a bit wider but without a wide heel.
Style Fan -- the jeans are from Rag & Bone. The wash is Sheffield. I normally wear a 27 in Rag & Bone skinnies, but sized down to a 26 in these. In the photos I just put them on after washing, they do slouch/stretch more from wearing but in a most delightful way. Some jeans stretch in annoying ways (baggy butt, always having to pull them up etc). But these don't. This wash is from a few years back and I think it's been a best seller for them. I am surprised you can still get it at Revolve. If they had it in a 25 I would buy it (to achieve a true skinny fit).
Suz -- thanks for the compliment on my middle aged legs. And I'm glad I'm not crazy in seeing how the flash emphasizes the legs.
