to be or not to be?

So I bought this dress recently from BCBG, thinking it was a rehearsal dinner contender... And it arrived... and it's cute... but it is not right for the rehearsal. First of all, it's yellow. And yes, I knew this when I bought it. But I thought, "oh maybe..." But my colors are green and black. Not yellow. And I don't think I want to be yellow at my rehearsal dinner afterall, regardless of the prettiness of the frock. But I still think I like the dress. Not love. Like. And in this economy, should I keep a dress I like, not love, for an unknown event? It might be good for the wedding of a friend in the Spring. But it's a silk/wool blend, so it needs to be a brisk day when I wear it, lest I itch my stomach off.

Thus, I need your votes - to keep, or not to keep... that is the question... And if "to keep," then for what, pray tell?
