Boys 3-Piece Suits FAQs

What is a boys 3-piece suit?

A boys 3-piece suit is a coordinated set with a jacket, waistcoat and trousers. It’s a classic choice for weddings, ceremonies and formal events.

Does a 3-piece suit include a shirt and tie?

Usually no — 3-piece suits focus on the jacket/waistcoat/trousers. To finish the look, add a formal shirt and tie (or bow tie).

Should I choose a 3-piece or a 5-piece suit?

Choose a 3-piece suit if you want flexibility to style it with different shirts and accessories. Choose a 5-piece suit if you want the convenience of a full set.

What shoes go best with a boys 3-piece suit?

For the smartest finish, choose brogues or Oxford shoes. For a dressy slip-on, try boys loafers.
