I've made the call.

What's staying:
The Vince dress -- by popular vote.
The Haute Hippie dress -- because DH loves it. It's special, I will wear it less often, but it will be fun to wear knowing that he loves it.
Natori Feathers bra and panties, matching set in Ayame: Can you believe this is my only matching set? It's lovely. A gorgeous color. And I ADORE this bra.
Someone - Diana? - said they use NAS only for special items and basics. I feel like that's the right approach for me too. That's exactly how it worked out for me this year.

What's going back:
Both sets of oxfords. Not a great fit for my feet, and very stiff. Possibly a larger size would work, but I'm going to wait. I don't think a black oxford will be a HEWI this year.
Not at NAS, but I also tried and am returning Angie's new G-Star painted white moto jeans. Cute but not fab on me. I am sure they look MUCH better on Angie. Enough said.

All in all, I came out ahead $$ wise, so I am quite happy. Thanks for all the help, my friends!!!
