This technique has three invaluable effects:
- It ensures that your collar tips and button holes will not get stretched out while in the laundry, helping them continue to lay flat, snugly button down, and retain sharp, clean edges all the way around. If you’ve ever had a shirt where you have to try to “re-crease” the collar because it’s riding up, it’s because you’ve been washing and drying them with the collars buttoned.
- The collar’s buttons avoid being subjected to undue stress during the wash cycle, which will subsequently reduce the chances of the button’s stitching later coming loose at an inopportune moment.
- With the collar unfastened and flipped up, both sides of the collar (particularly the oft-neglected underside of the collar crease) will get thoroughly cleaned (and dried).
The benefits of this practice may not be immediately obvious the next time you check yourself out in the mirror but your collar will retain its off-the-rack crispness and fold for a much longer time, which is a priceless feature for a wardrobe staple like a button-down shirt.
Bonus tip! In a crowded closet or cramped garment bag, flipped-down collars can get flattened, deformed, and creased. So, after washing and drying your shirts, hang them with the collars flipped up to ensure they remain pristine while in storage.
