I think such loose, a bit baggy blouse is a thing that everyone should consider buying this spring. Can be sheer, Can be silk. It would be one of my must-haves, but I already have like three of them...
One more thing every woman should have, there is nothing more classic than trench, suits on every occasion. I bought one recently and I am even happy when it's getting colder (first time in my life), so I can wear it!!! And imagine how great they look with brouges, just classiest!
