I love that the first thing you notice about this lady is the beautiful color combination of her look or her accessories but it takes a while to recognize that she is a big woman. I had a conversation about this the other day with a woman who was very frustrated about her lack of choices in designer clothing for a woman over a size 12. She is absolutely right but until the stores catchup with the demand(if they ever do) then don't make it about the clothes, make it about the accessories. If you can't buy a Dries Van Noten top in a size 14 then buy the Dries Van Noten scarf and keep the clothing as the backdrop. To me, that is what the woman in this photo is doing (although the dress is very beautiful) -she is making her look about print, color, accessories and exotic drama.
I used to live in Murry Hill , the Indian section of Manhattan, the woman there use a very similar method of color, wrapping and accessories and they often look amazing.
