If dressing everyday is getting monotonous for you, you can easily break-away by dressing old school with a li'l bit if funk, boy.
No! Dressing funky doesn't necessarily ask for stocking funky pieces in your wardrobe. Begin achieving this goal by experimenting with the ones you already own.
Matching a well-structured semi-casual suit with a pair of white leather sneakers is a sure-shot way to turn heads. (Think Tranquillos). Add details by cuffing-up your jeans/chinos and the sleeves of your shirts.
Hide your socks to show your ankles until you invest in a funky pair.
Mix-match prints of torso and lower yet make sure they're subtle.
Later, invest in good quality accessories to amp-up the look - like suspenders and colourful shoes.
Keep experimenting to add some funk to your old-school look.
