For seniors and people with physical challenges, there’s nothing worse than having to fumble around with button holes and zippers when it’s time to get dressed. Of course, dignity is an issue as well. Who wants to be out in public with an open fly or unbuttoned blouse because your fingers are too stiff to do them up properly?
You could try to ‘retrofit’ clothes, and while the result may be functional, it might not look the same as typical clothing. An ideal choice is adaptive clothing which is attractive, but made in a way that an elderly or disabled person can manage. To the casual observer, the clothing is attractive and looks no different from regular clothes.
