I saw a picture of Taylor Swift wearing this top in September's issue of In Style magazine (the one with Hillary Swank on the cover). It's a Lauren Moshi Devon Bow 3/4 sleeve boyfriend tee. I think this top goes for $126. A bit too expensive for me.
As soon as I saw it, it reminded me of a blouse that my mother-in-law got for me as a visiting gift last week from Charlotte Russe.
The top is also available in medium gray (which is the one I have) and the bow is white with navy blue stripes. Although the length of the sleeve, cut of the neck and material are different this top is still a good inexpensive alternative to the first one. The price is $14.00 which compared to the $126 is a steal.
