How to keep shirt collar's stiff without ironing?

If you just expect to wash your shirts and wear them un ironed

Then they will look curvy

For a nice crisp stiff collar you need to spray starch and iron it

Otherwise you will end up with a creased shirt and a curvy collar

I,m not surprised your a bachelor ?

Ironing really isn't that hard. But if you are bound and determine not to do it, here's a simple way to deal with the collars.

After washing your shirts, toss them in the dryer for 2-3 minutes - just enough to "relax" the wrinkles. Take them out of the machine damp, hang them up on a hanger and then "snap" the buttons and collar straight with your hands. Let them dry in that position.

Spray starch will not work by itself. Sure, it will stiffen the collars but it will not straighten a curved collar without ironing.

Collar tabs work if there is a slot under the collar. The best and easiest way is to iron and starch the shirt and collar. Starch the underside and the top side. The collar and shirt would look the best then. Of course if the shirt and collar is worn it might be time for a new one

yes, spray sizing or starch.......in the laundry section.
