I asked my MoHs to just buy chocolate brown dresses. They are two very different women, so I thought this would be the best option. I did not ask for any specific length, but Sasha said she was going to get a full length dress. (Both of them don't like their legs and don't want to wear heels.)

I showed my sister a few dresses and this is the one she wanted. This is from GoJane bought through Amazon.com

Sasha ended up buying this dress from David's Bridal.

Despite the girls long dresses, we're not having super formal attire for the guys. Matt really did not want to wear a tux. I personally think most men seem really uncomfortable in tuxes when they're not used to it. They are wearing black suits, white shirt, which I assume they will own or not mind owning.

It will be something like this, orangish boutonniere and all.

Despite what the groomsmen say, this tie really doesn't look as 70's as it looks in the photos. We bought two from thetiebar.com. I am pretty sure they will look great and neutral.

 Matt wanted a really bright colored tie (no champagne or other bridal type color for him). I talked him down from his neon blue to burnt orange.

This is the tie we ended up ordering off thetiebar through Amazon. We also ended up ordering the matching pocket square for Matt, since he does not want to wear a boutonniere.
