I don't travel with suits, etc but I find to baseline suite similar to a large packing cube. If you wear any type of casual pants or long/short sleeve shirts that suite holds a lot of clothes and they will remain wrinkle free.

I first stack all my pants on top of each other and lay them in the suiter WITHOUT hangers. Then put all the shirts on top the pants and arrange the sleeves so they aren't sticking out. Then I put any other articles of clothing depending on the room left. Then I fold and zip the compartment up as a large package cube. When you get to your destination put everything on hangers. Try packing your regular clothes in that suiter and see how it works for you. I mainly pack hiking clothes in there. And I use the entire setup including the roller bar.
