Thanks for the feedback.
The idea was trying to differentiate myself from other sellers. So far, I have not seen anyone auctioning complete outfits (it could be because it doesn't work!). I have gotten great feedback from people that love the outfit concept.
I offer the ability to choose alternate shoes if they are not in the right size as this was a limiting factor. I think possibly it got left off some of the listings and I need to go back through them.
So far, I have had a couple of people ask about alternative shoes but not one person has taken me up on the offer. I try to pick average sizes which are somewhere between a 7 1/2 to 9. I am assuming that covers a lot of buyers.
I could be completely off base on this.
