STYLETHREAD -- LET'S TALK SHOP!

I recently got this two tops from Bluefly on sale.  I like the teal one in particular but am not sure what to wear it with:

(this is a dark purple with gold metallic threading.)

any advice on outfits for either or both of these?  also, i think both are a little too big so i might send them back for a smaller size.  they won't be at the sale price any longer, and i feel less enthused about paying full price unless i have some really great outfits for them.
