I'm trying to mature my style whilst keeping somewhat casual. I do want to use a blazer as I honestly love them so inspiration around them would be cool. As for my current items I have recently got a blazer from Zara as I'm on a limited budget been a student.

I also got a shirt from French connection and a pair of trousers from Asos.
I think I may need to send the trousers back and get an inch or two shorter to go for the look that the model has.

TL;DR: How does these outfits look and what improvements would you have?
