Style Summer Work Outfits

Styling summer work outfits are the worst.  You want to be comfortable, but its hot so you want to wear less, consider it is work and you want to be professional looking.  I try on at least 3 different outfits a day.  Some suggestions:
 Flowy blouse and short pants
 Black pants and a patterned dressy tank top.
 White pants and a loose 3/4 sleeve top. Sailor pants and wedges.
 A loose flowy dress with short sleeves.
 Floral dress
