I Need Therapy.

Eleven weeks until ones wedding is enough reason to start getting nerve racked but add into the mix a long list of things to get done and you have a recipe for a jittery bride. I am going to admit that I have started to feel the pressure. No one has really urged me to get on the ball, which I do appreciate, but my sisters have now let me know there are things to get done and not much time left before the big day, which I may appreciate more. I can't seem to make a decision on anything. I had my sister purchase her bridesmaid dress which was a simple black one from Davids Bridal and now I am thinking I made the wrong choice (and feeling pretty awful about making her spend money on something I am unsure of, but I will buy if back from her if we don't use it)! I saw someone else post a picture of dress number one on their blog and I fell in love!My bridesmaids aren't six feet tall and five pounds light, so I don't know if that dress is a good option or not. Dress number two is alright but I am not sold. I am just altogether uncertain of any attire agreement and can't picture all this coming together. If I do go with a floral print dress then should I change the black suits and general color combo (black and green)? It's driving me even more insane!

Edit: Below is the black dress I very confidently told my sister to buy. A very simple dress yet somehow one of my (very picky) bridesmaids hates it. It doesn't get more generic than this. I also added in a picture of where the ceremony will be held. It will be in late May about six o'clock in the evening.
