Unfortunately, that t-shirt happened to be my Full House graphic tee I stole from my friend. Yes, it does say "You Got It, Dude" with a picture of a young Ashley/MK Olsen on it... anyway, it was comfortable and it oddly enough wasn't met with as much mockery as I expected. I wore it with my burgundy skinny jeans and a chunky cardigan, and added some cognac coloured booties to dress it up a lil bit.
To dress up a graphic tee, I really like throwing a blazer over it and pairing it with either some leather leggings or boyfriend jeans (quite a contrast, but both look good!) and some pointy toe pumps. I would probably swap the yellow Full House one for a more muted colour and more mature print, but the overall effect is very chic and crisp! Or ditch the blazer a la Cara Delevingne, as seen in this photo here.
