There is a packing system made by Eagle Creek that has a special piece for shirts and suits, and shows you how to fold them.
My husband has a Henty bag for his suit.
He says…go to the Henty website…there are lots of options and videos to see.
This is what my husband has. Available from Amazon also.
The roller board suitcase we bought that is a Briggs & Riley has a very nice area of the suitcase to hang your jacket and you can fold the trousers as well. S has been using his suitcase for years and it works like a champ. H and I have similar bags and my blazers, shirts and slacks never wrinkle. H’s suits and outfits don’t either.
The Henty bag looks very nice but it’s also $271- the method BB outlined upthread works very well .
Here’s Men’s Wearhouse rollup bag for $149, and 50% off the 2nd one.

I believe I bought this for S but he prefers having his roller board to accommodate his suit and wheels whenever he can.
My husband got the Henty bag on sale someplace.
I know several people who have happy with this
