Like many of you, I'm sure, I've got tons of favourites, among which some I will eventually purchase.
The main question remains "will I really use it, wear it, or find a nice place in my house to display it"
This being said, of the favourites I have and that I will buy, what would deter me is the description: if it is not elaborate enough (not enough info on materials used nor sufficient mention of dimensions), I might find something similar somewhere else.
