-oversize plaid top(tie it in the back you want it loose fitted and not swamping)
-oversize blazer in black/grey(didn't wear one here since it so hot so got for a waistcoat if you'd like)
-HEEL's and not Converse!(to keep it luxe, you need the feminine elements)-preferable brown or black Ankle Boots
-Messy hair a la Mary-Kate (i ain't saying Courtney cuz hers is just nasty)
-Oversize leather bag
hmm...that's all? might have missed something.
Oh and keep accessorise at a minimum (could be a male watch a single neckles -gold on red shaded plaid and silver on Blue)
