Garment bags are a classic way to transport suits, dresses and other garments to prevent wrinkling. These bags can also be used to store garments from dust. A garment bag or suit bag can be bi-fold (one single fold) or tri-fold (folds into itself 3 times, to enable it to fit as a carryon). Most garment bags use a common household hanger inside it, for convenience. Search through some great garment bags below.
