I think the best part about wearing a T-shirt dress is that you feel like you're wearing pajamas. They are so comfortable. And finding an item of clothing at this comfort level that makes you look put together is a major bonus. Plus, you can dress it up for a night at the country club (as I did last week), or you can dress it down when you're just around town or hanging with friends.
Though I own a few T-shirt dresses, this one from Brandy Melville has been one of my absolute faves this summer, and it will definitely carry well into the fall. To prove it, I styled it two ways, one summer look and one fall look.

Overall: Yay for T-shirt dresses! 10/10 recommend.
PS. If the Brandy Melville dress isn't doing it for you, my other favorite one is from Old Navy. The one I have is super old, but one of my friends went to Old Navy this past week and said they still have some cute ones. Happy shopping!
