Sometimes when I am window shopping at "discount" websites I find that there are many good and cute dresses that would be perfectly suitable for bridesmaids gowns. While you can usually find cute looks at prices less than bridal retailers, the downside is that the quality may not be the best.
In my opinion the looks work better for a wedding if they are longer midi or maxi lengths. Here are a few options I liked from Topshop.
