How do you wear a blazer with jeans?
Three rules: a textured, relaxed blazer rather than a suit jacket, dark jeans with no rips, and leather shoes. Keep the collar open and let the blazer end around your thumb knuckle.
Blazer: single-breasted with a notch lapel, in a texture such as corduroy or tweed, in navy, grey, khaki or brown. Patch pockets help, because they tell the eye this is not half a suit. Jeans: dark indigo or black, slim or straight, clean hem, no fading at the thigh. Shoes: leather. Brogues, loafers or Chelsea boots; minimal leather sneakers only when everything else is sharp.
What mistakes should you avoid?
Five: an orphaned suit jacket, light or distressed denim, a blazer that runs past the thumb knuckle, chunky sneakers, and a tie. Each pulls the outfit toward either a suit or a gym bag.
The suit jacket is the most common one; the sheen of suit cloth gives it away next to denim. A tie is the second, since with jeans the collar stays open.
What size blazer should I buy?
Your usual jacket size. The blazer runs XS to 3XL in seven sizes and the knit alternative runs S to 2XL. Adam & Westcott publishes no inch chart for either, so go by letter.
Check three things when it arrives: the shoulder seam sits at the edge of your shoulder, a little shirt cuff shows at the sleeve, and it buttons without pulling into an X. For how the letters line up across the store, read what size jacket should I buy.
What goes with a blazer and jeans?
Four pieces cover it: the blazer at $79.98, a knit alternative at $49.98, brogues at $49.98 and a brown leather belt at $39.99. Match the belt to the shoes.

Yes. A textured, relaxed blazer with dark, clean jeans and leather shoes is a smart casual standard for dinners, casual offices and relaxed receptions.
What colour blazer goes with jeans?
Navy first, then grey or khaki. The Notch Lapel Blazer comes in navy blue, black, grey and khaki, and in corduroy even the black reads casual rather than suit-like.

Brogues, loafers or Chelsea boots. The 
Wingtip Brogue Oxford Shoes cost $49.98 in US 6 to 14. See how to wear wingtips.
