Frequently Asked Questions – Boys Suits

What’s the difference between a 3-piece and a 5-piece boys suit?

What should a page boy wear to a wedding?
A coordinated set such as a 3-piece suit or a smart 5-piece suit is a popular choice. Pick colours that complement the wedding party for a polished look in photos.
