We’ve all seen how many of the designer/mass-market collaborations get toned down to appeal to the, well, mass markets. But I think this goes against the whole strategy at the collaboration’s core.
Why should Payless even bother to work with and support a designer like Siriano who can help them tap into a new fashion-forward audience with the pieces he shows on the runway…

… and then water them down to the point that they bear no resemblance or retain any of their interest or appeal.

I don’t normally shop in Payless because the style isn’t usually there. But I have bought four pairs of their Lela Rose line and like them very much.
I know Christian’s style is more extreme but they could retain something from the runway.
If they aren’t going to commit to the styles then just don’t bother!
