Through the Grapevine

Mr. Fantastic's family is hosting an engagement party for my brother in law and his fiancee in a few weeks.  Yesterday, my in-laws and I went to do a site visit and get the venue secured.  The party will be held at a local vineyard and winery.  I wore a grape colored top as a nod to the vineyard.

Camisole: H&M (old); Top: Saint Tropez West (old)

Skirt: Trina Turk for Banana Republic

Sunglasses: c/o Toms

Necklace: Express (old)

Bracelets: c/o Y&I Boutique in Dallas

Bag: Rebecca Minkoff Amour (gift from Mr. Fantastic) 

Shoes: Manolo Blahnik Sedaraby (old)

The Trina Turk for Banana Republic collection really blew me away this summer.  So many of the pieces were fun and versatile and I ended up with more pieces than I initially anticipated.  I really blame the blogging community for my uncontrolled spending. ;)  I loved the way Kelly styled this skirt over the summer and I was happy when I found it on sale in my size last month.  I've worn it a couple of times, but never had my camera with me.
Initially, I thought I would wear a pretty cocktail dress with nice heels and clutch to the party.  After the site visit, that is out the window.  The parking lot is all gravel, the walkways are sloped and uneven, and we will all be sitting outside in the grass.  Heels are definitely out.

Any ideas for what to wear? I want something a step above casual, but definitely comfortable.
