A great fitted white shirt is a staple in every fashionista’s wardrobe. But,
when you have fine motor issues, all fasteners are a pain in the a##; especially buttons.
You can use a button helper (metal tool found at home health type stores. But, they are time consuming to use. Instead, I have all my button downs sewn up permanently by a local seamstress. I always leave a few open at the top and buy shirts with plenty of stretch in the fabric so that I can easily slip them over my head.
