Leave it to 
Petra Mack to make a 
blazer and 
jeans look insanely cool. So cool, in fact, that it 
got over 31,000 likes on Instagram. The best part is the 
spring outfit is incredibly easy to pull off. All you need is a navy 
blue blazer, a 
black t-shirt, 
high-waisted jeans, and strappy black 
flat sandals.
