Preen Shell Jacket ($1,325)
Why it's a back-to-school must: It's clean, sophisticated, and screams "cool girl." The impeccably tailored lines, stark two-tone contrast, and tuxedo-inspired hemmed "coattails" make it a structured blazer worth adding to the arsenal.
How to wear it: It would be a disservice to the minimalist nature of this tailoring to go overboard on styling. Thus, we see this blazer being worn with a slouchy white t-shirt, black coated wax jeans, and flat zippered ankle boots.
