I'm attending an evening concert/live DVD taping in Chicago next week. There is no dress code - people attend this group's concerts in everything from very casual (jeans & tees) to occasionally semi-formal. Since it's Chicago I'm thinking there will be more semi-formal attire than usual though. I bought this basic black sheath because I wanted something versatile that I could dress up or down depending on the sash and accessories.

Here's the ensemble I am came up with:

I was originally going to tie the sash like this, but I think I prefer the bow:

My concern is if the sash is enough of a statement piece by itself? I don't want to ruin the "pop" effect of the sash, but since the rest of my accessories are rather plain I'm worried about it being a bit boring. I would prefer a glitzier clutch, but I went with this one (which has some pintuck detailing on the front that you can't see) because it fits the bill of being able to carry my camera safely. Also, are strappy sandals more formal with heel or ankle straps, or are slides equally okay?

I'm pretty much out of time to shop for anything else at this point, but I would appreciate some opinions on if this look works, or if I really need to change something! I want to get the details right because I rarely get to dress up like this and it's a special night.
