What should I gift to my sub?

I want to give my baby something for her to come home to when she gets back from her trip, she’s been expressing that she wants a collar and I want to give her one. I just simply don’t have the funds to get a proper one at the moment. I’d like to get her at least a choker for right now but I don’t have the funds. Does anyone have any suggestions on what I should give to my girl?
