This shirt is uber popular among celebrities, from Kristen Stewart to Jessica Biel to Emily Blunt (just to name a few). It's the perfect throw on with anything top, and gives a casual chic pop to any look whether you're going 'punk' or 'classic'. The actual Rails top runs for just under $100 whereas Forever21's is under $20, I'll take one please.
