She definetley has an interesting blend, all the pieces same a similar pallette yet all seem to be of a slightly different, but consistently classy and toned-down, fashion.
The first dress is really traditional, but the intersecting trim works well to highlight the model's curves, although perhaps the center should have been lower. I'd be interested in seeing how it looks from the back.
The second dress is a more trendy and youthfull. I like the idea of the black accent on the top, but it does not seem to come out so well. Also the ruffles not coming all the way down leaves the garment looking unfinished. The skirt is outstanding however, the pattern is clean and perfectly placed. The black/white contrast works exceptionally well here.
The third dress has a great cut up top, but perhaps it should have been longer. I am not the biggest fan of the circular pattern on the lower half.
I am quite the fan, however, of the hat and the fourth dress. Simple, seductive and playful. Well done.
