3 ways to look dressed up even when you don't have a suit

The simplest way to avoid or approximate a suit is to just put a blazer on over your dress shirt. A blazer can be worn with or without a tie, and a jacket will make you look a lot more dressed up than any other item (besides a suit itself). Many blazers have an additional lining and are structured, too, which ups the factor of dressiness by an additional degree.

Add great tailoring and a pocket square for additional class.

An open-button sweater can look almost like a jacket, provided it's the appropriate type. We recommend a fine knit with a shawl collar, which can most closely approximate the look of a traditional suit jacket.

If you're feeling underdressed, add a tie that can hide underneath the front buttons of your sweater, just like it would on a jacket. Some manufacturers even sell "sweater blazers," which are exactly what they sound like: sweaters that are fashioned to look like blazers.

If you'd like to do away with ties altogether, take a note from James Bond and get yourself a roll-neck sweater. There's just something inherently dressy about a turtleneck with a blazer over it, and if you have the neck to pull it off, there's no reason why you shouldn't give it a try.
