Guys spend on dress shirts and suits to look smart, while girls spend it on shirts that are not neccessarily the most practical things in the world, but are definitely the prettiest. 
I adore these two from Chloe. The white pleated one is great for the day time, but I especially adore the silk one, which looks so classy. They have it in many other colors too and they ALL look fab I hard a hard time just choosing one! 
Vanessa Bruno also makes gorgeous pretty tops. The light blue one with the pretty butterfly sleeves is perfect for a casual day out and the vibrant electric blue one on the left is a Harrods Girl favourite. 
For oodles of details, frills and layers, there are these two Grecian top from Anna Sui and Emilio Pucci, which is both elegant and fun.
And these two black and white ones from Paul & Joe and Marc by MJ. Although I must say, this Marc by MJ one does not work for everyone.
A little simpler but just as beautiful, there are these two from Bellekat and Development.
For something a little edgier, these two from Zac Posen and Sass & Bide are just the thing.
Pretty things are imminently impossibly delicate as well. These two from Anna Sui and Robert Rodriguez are a perfect example of that.
Oh and they are almost always amazingly expensive too for something with so little fabric. But they are all just oh-so-gorgeous!
