I was looking at dresses on Overstock where I normally find an incredible selection for all sized women, so I was surprised to find there are some designs that still need to think more flattering in this day and age. Just my opinion.
The blue dress (left) with the pleating on the skirt that takes away from the beautiful top.
I found the 2nd dress (middle) to have a lack of focal point due to the color and plain wrap design. Women of all sizes have things they wish to hide and this dress does not do that! In fact the focal point is on the stomach and hips of this lovely large lady.
I see what the designer of the third (right) dress was trying to do, but this dress is not very flattering to the booty. There is too much directive pattern and the color is making a nice booty look.. well I will let you decide.
