It might be tempting to reach for your go-to, black-wool suit every morning, but trust me - show up dressed like that during the summer months and you'll look like you haven't checked a calendar in eons.
So, may I suggest this fabulous white, sleeveless Gerard Darel suit I recently happened upon?
Notice that because you're showing more skin (your arms), you'll want to keep the rest of the suit loose. This balances the bare-arm to maintain a sense of professional decorum. Leave the fitted, nipped/tucked, sleeveless outfits for the Miami Beach clubs.
Pops of color (blue blouse and saffron purse) keep the suit from looking too plain or stodgy:
Tip: I wore the same color shoes as the pants to elongate my legs:
This suit is a wonderful alternative to traditional office garb and its airy design keeps you cool in hot weather. I like to think that its free-flowing lines emanate a billowing Gehry, but that just may be wishful thinking.
