I am looking for maybe a white dress not too long or short. The photos will be taken in my cousin's field with huge oak trees. i was thinking of maybe something flowy and delicate looking.

I've attached a few suggestions for flowy white dresses that are about knee-length or just above.  The first is the Moss Sup Co True White Tube Dress from Target.  It's very cute and comes at a relatively low price ($13.98). 

The next one is the Sangria Dress by UjENA from http://www.eCrater.com It's great overall and kind of reminds me of Marilyn Monroe.  This dress is right at knee-length and can be purchased for $69.

Finally, we have the White Lined Sun Dress from http://www.Overstock.com This one is probably my favorite, as it looks cute, flirty, and fun all at the same time.  I think it would be a great picture-taking dress. :o) It can be purchased from Overstock at $67.99.

I hope these dresses are something like what you were looking for.   Either way, I'm sure you'll look gorgeous in your pictures!
