White after Labor Day?! 
White and neon pistachio green stilettos?? Perhaps she's going for a summery FL look. Dressed inappropriately to me for this time of year to me, but she'll fit in with all the tourists. Right now it's cool this morning and we will reach the 80's by afternoon. A little chilly for me right now, but for others the weather is perfect.
It seems though she's worn the dress before with bright pink stilettos??
