A boyfriend tee and Flared jeans compliment each other pretty well in my opinion.
It's a very casual look.

You can get boyfriend tees at vintage stores, at the boy section (in any clothing store), or just steal one from your boyfriend or brother. Haha.
I got my boyfriend tee from my boyfriend. He has the habit of shrinking his tees in the washer, which usually means, I get a new tee.
So it's kinda a win-win situation for me.

Flared jeans also give that 70s vibe which is always a good look in my books.

Where do you get your boyfriend tee?
