Summer officially ended on Labor Day.
As long as it is warm enough, wear the sleeveless, the sun dresses, the open toes, the shorts (Oh! don't get me started on the shorts, again!), and anything else that resembles summer wardrobe pieces.
Celebrating the 'end' of summer means one thing for reversecommuter - hit a patio!
P.S. margaritas help keep away any chills quite effectively :)
