Weddingbee boards

Hey ladies :)  I just bought a couple of dresses to wear as a guest to upcoming weddings, but I can't seem to find shoes I love to go with them!  I know all you fashionistas out there can help me :)

Both dresses are JCrew's Cotton Cady Lyndsey dress, cuz I'm boring like that and JCrew's having a sale (code extra20 for 20% off final sale items).  One is in "fresh mint" - I got this one for an afternoon at home reception being held at the groom's parents' home.  The other is black, for an evening wedding.

I'm not a regular heel-wearer, and I need to be able to walk around and dance, so something with maybe a 2.5 inch heel would be best.  I wear a size 8, sometimes a 7.5. I'm hoping for under $100, but if I really love them, maybe I'd go to $125.

To give you an idea of what I like, I love these for the black dress but they don't have them in my size (8, sometimes a 7.5).  I adore these, but I wouldn't be able to walk.  And really, who doesn't love these, but they're just too much $$.

Can somebody please help me out?  Suggestions?

I'm not a regular heel-wearer either, and I find the key to wearing heels comfortable when you're not used to them is to find an ankle strap or slingback style. Some ideas along that vein - in metallic colors that you could wear with both dresses -

I'd also try TJ Maxx or Marshalls - they usually have a good selection of Nine West, Cole Haan, etc for great prices. I have much better luck at those two than at DSW.
