Here are a few looks I've put together for you:
The office guy
You wear a shirt, you wear a tie, whatever. You wear an overcoat outdoors. You may be a bit hesitant to deviate from the sea of black, blue and gray but why not start with injecting a few pieces with a different color?
Victor coat from Rag & Bone. Wool herringbone, cashmere collar.
PS by Paul Smith Hawaiian girl print shirt. Yes, we're looking forward to summer.
Silk knit tie from Drake's.
Jake suite trousers from Theory. Slim-fit, lightweight, stretch-wool construction.
Go brogues but a bit rogue with a lightweight sole. Lunargrand longwing borgues by Cole Haan.
Ben Minkoff Devin tote. Yes, let's go a little classy here.
The casual dude
For the "dressier" type of casual guy. Talk about white, black, and blue.
S.N.S. Herning loop sweater. Don't you just love that wrinkled effect?
How about let's put on a crisp white shirt underneath that stylish sweater? Oxford button down shirt from Apolis.
7 For All Mankind Slimmy Slim Straight Movember jeans. For each purchase, $20 goes to the Movember Foundation in support of men's health.
Stretch woven leather belt from Anderson's.
Torn between your backpack and being dressy? Go leather with Marc by Marc Jacobs.
Grenson Archie triple welt wingtip oxford shoes. No, they're not black; they're blue!
The go-to bro
So suits and ties are not your thing, nor are wingtips. This could be the look for you. Think joggers, a parka, and adding some zing with red kicks.
Gavin puffer jacket by Mackage. Puffer-style body, leather sleeves.
T by Alexander Wang long-sleeve linen T-shirt.
Layering with T-shirts. Killa Whale T-shirt from Insted We Smile.
Zanerobe Dynamo pants. Drop-crotch, contrast ribbed cuffs.
Yup, some color. TSA woven high-top sneakers from Filling Pieces.
Or you can just go put together your own look with tons of pieces over at East Dane.
