What’s a Pajama Suit?01

How is it different from conventional suits?

Differences from conventional suits


The silhouette is slightly more relaxed than a standard suit and is semi-casual wear.
The jacket has patch pockets instead of flap pockets which makes it look more casual.
The suit has a clean and beautiful fabric surface that you can enjoy combining with a wide range of other outfits from ties to T-shirts.

Differences in silhouette


The fabric of this item has clean look. The unnecessary details are reduced when designed so shoulder pads and lining are taken out to make it look more casual compared to a standard jacket.
This is one of the reasons why this jacket is so versatile.
