IMO, the blue grey gown looks great because it does not have the usual midsection or bands. I like the dress is one piece. It flows rather than the usually chopped up dresses from Bruce Oldfield.
I do think it would look better if the gown was all one material. The lacy see through arms and top look odd but she is headed in the right direction.
Next time, hopefully, we will see an evening gown that is all one material without the seams or bands or the see through lace over the arms and decolletage.
This dress is an improvement over the gowns with a bit of lace on top.
This gown the lace is from the neck to the floor. Now she only needs the dress/slip of the gown to reach the neck and arms.
