Need Help

Last Sunday I picked up two items from Target, and I'm not sure if I should keep them.  I really wanted something from Zac Posen, but the line wasn't as good as expected.  If the dress I bought had cost $20, I wouldn't be debating it at all.  But at $30, I'm not positive.  I like it, I like that a tank dress is actually flattering on me (a first!)... And the shoes are a good price, I'm just not sure if I need another pair of sandals.  In order to help, I put together an outfit that would work with the items.  I actually really like it together.  I'm already dreaming up other outfits for these.  Let me know what you think!

Dress: Zac Posen for Target
