Here are two inexpensive dresses I recently acquired--one black, one white--to wear to work this summer.
A black dress
I know it doesn't look like a summertime dress, but it's made of thin rayon, so it's light & comfortable.
I've been wearing flat sandals everywhere--even to work--which I think helps make the dress look a bit less serious.
Modest wear is becoming popular internationally. See article about this rising trend here.
A white dress
I figure I'll be able to wear both dresses into the fall. I'll just throw a cardigan over the white one & change shoes for the black one.
What are you wearing to work this summer?
