As you adjust the sleeves, be careful not to pull the side seams of the shirt towards the back. You are just folding the sleeves in at this point, not the core of the shirt. If you have a short-sleeved polo, you will still fold the sleeves toward the middle of the back of the shirt. However, the sleeves will not overlap in the middle.
If you have a short-sleeved polo, this fold will help to keep your sleeves in place moving forward. Make sure to hold your sleeves in place as you complete this step or they may move around as you lift the sides to fold inwards.
The final roll should be around 6 inches (15 cm) in width.
It’s also okay to hand wash most polos, as long as you stick with the same suggested water temperature.
Be aware that drying your polos on a rack might make them look more wrinkly. However, this can be quickly fixed with a round of steaming or ironing.
You can also hang up your polo and use a steam machine to work out any wrinkles. Pass the steamer wand close to, but not touching, the fabric until it smooths out. Polo shirts have a tendency to get particularly wrinkly around the collar, so pay additional attention to this area. Also, make sure to reinsert any collar stays after you are finished steaming or ironing your shirt. [14] X Research source
