This Arrow fan art might contain
fedora, felt hat, homburg, stetson, trilby, dress hat, high hat, opera hat, silk hat, stovepipe, top hat, topper, and beaver.
Basically highlighting both of the relationships with Oliver/Sara and Oliver/Felicty. This video is sort of Sara/Oliver are the past present, and Oliver/Felicity is the present-future. I love both pairings.
