Roped Ruffles

It would seem I'm in a bit of a predicament again with one of my purchases and I need a bit of advice from my trusty readership. I snagged this lovely blue Tucker for Target dress the other day for under $10, the only issue is it's a size large, 90% of the time I'd say I absolutely can make it work (and you've seen me do it here & here with this size 12 French Connection dress). But since I'm still shedding my baby weight I'm on the fence about the dress. I first tried it on with a skinny belt and loved it, but made the mistake of asking my husband what he thought and now I'm having second thoughts.
