STYLETHREAD -- LET'S TALK SHOP!

OK guys, sorry in advance for the long post.  I have three separate events coming up in a few weeks that I need dressy-ish outfits for: an awards day/luncheon, a mass, and a graduation.  I'm going to wear dresses to all of them just because it's easy and I want to .  I already have some stuff I can use so hopefully I won't have to buy three head to toe looks.

Possibility #1

This dress (it's a sheer brown chiffonish type material over a beige underlayer) with _____. 

I need new shoes for this but I can probably use old jewelry.

Possibility #2

This dress (navy mesh-y, very slinky and sophisticated) with ____.

I wanted to wear it with SM Magnolias but I missed the boat and they're all sold out.  I even called around and everything .  So some sort of interesting shoe and maybe a thin belt at the waist (it used to have a ribbon tie but I like it without)?

Possibility #3

-New dress

One of these shoes (these are my comfy heels):

(brown and much less contrast-y IRL)

Leopard d'orsays

or

gold t-strap sandals

So basically I need a pair of shoes for the brown dress, a pair for the navy dress, a dress to go with my shoes or 2 new pairs, and whatever other accessories I can get for about $250 (less if possible but I can go a little over if needed).  I know this is a lot but if you could even just post cute shoes you like, that would help me a lot.  Thanks!
