Banana Republic has beautiful silky (not sure of the material) navy/indigo strapless knee length dresses for $65!!!! They were originally $175. I bought a bunch at the Kittery Outlets (they had a ton of sizes there) on Sat for $110, went back to the Wrentham Outlets today to exchange a size and they gave me a price adjustment on all the dresses b/c of the 40% entire store sale. When I originally bought the dresses I opened a BR credit card so I got an additional 20% off. The Wrentham Outlet does not have as much of a size selection but you can buy the dresses up in Kittery over the phone and pay a $5.00 shipping charge.
Hope this helps any brides who are looking for this color and style dress!
