How to wear a blazer as a top

It's been months since I wanted to style an outfit with this blazer. I bought it 4 years ago for my graduation and never worn it!
The last years it is common to wear blazers, with a tight belt, as top and I thought that at this way it would be fantastic.
Furthermore, white is an amazing color to wear all the year long and match it with everything. Would you wear a blazer like this?
