I received my Le Sac dress a few weeks ago and was eager to try..but was turned off by the choice strap color ( black dress, electric blue straps) so I made a b-line to the Hilcrest AmAp and they had some sac's in stock. I picked up the same dress, black straps and fell head over heals. Since I saved all the potential "looks" , I started to try them out..then while trying to un-tangle myself found that - the strap is not as long as their model perceives it to be. Luckly the styles didn't strangle the life out of me but I still love the dress.
