Basket of flip flops vs. slippers for reception

I want to supply a basket of dancing shoes for the ladies during the reception and, while I know most brides use flip flops for their baskets, I am wondering about the ladies who will be wearing hose or stockings. Flip flops won't really work for hosiery. I know ladies don't wear panty hose as much anymore, but lots do especially for a very formal event.
Should I do slippers instead or both? Also, it seems like slippers will be way more expensive.
Any thoughts about this? Any ideas of good resources for slippers? I am thinking of those very simple Chinese style slippers that have a sole but are meant for indoors generally.
Thanks for your ideas in advanced. This has me stumped!
