I am looking for a black bridesmaid dress for under $100. My MOH prefers to stay in the $50-75 range but will go to $100 if she absoultely has to.
I am willing to buy online because we have had little to no luck at malls or department stores.  She wants something with straps, cocktail like but prefer down to the knee. I am putting a red sash around the waist of the dress so it has to be able to have that tied around it. 
Does anyone know of any good online websites or stores to check out? Or have you seen a black dress that fits this description? Please share!
Thanks!!
