The logo look like a diamond, which is a feminine symbol, proof of quality and profesionalism. The choice of the colors is made to attract women of all ages. Finally, the straw on the right suggest an idea of fun and party, thats why the diamond could be a cocktail glass too.
As for my previous logo, with a black background, I wanted to create a "feminine" logo, but with a white background. Indeed, some people prefer white backrounds to black ones.
