Not that anyone asked me, but I thought I'd take a stab at coming up with a better Ralph Lauren uniform for the US Olympic team:
Dress - Celine pleated wrap dress. These women have the best figures in America...they deserve to show them off a bit. A wrap dress is flattering on everyone from the tiniest gymnast to the tallest basketball player.
Belt - A navy wide belt.
Shoes - Basic peep-toe navy wedges.
Jacket - For people wanting more coverage. Wear this linen jacket with the belt on top.
Shirt - A classic white shirt rolled at the sleeves. No gigantic Ralph Lauren logo.
Tie - Navy and red stripes.
Pants - Basic blue slacks.
Shoes - Brown slip-ons.
Belt - Brown suede.
That took me 15 minutes and doesn't involve any ridiculous sneakers, hats, ascots or logos. More appropriate for the hot weather and event, and also more like how Americans regularly dress.
