"Now, one may separately question whether there is anybody in the target market, who wants these clothes but won't drop the funds to just buy them, but I can't speak to that either way;"

I think that's going to be the problem. My wife used to work for families to whom money was pretty much no object. $42 and $16 are equivalent in their mind, and equal to about $0.25 to a family on a budget. I don't see them wanting the hassle of having to remember to return clothes within 3 months when it's effectively the same % of their income to buy them.
