Why it happens Brain changes impair the ability to weigh information and make decisions.
What you can do
Lay out a complete outfit.
Pare down the number of choices in the closet or drawers so as not to overwhelm.
Make sure to store outfits that are inappropriate (for the weather or the occasion) out of reach.
Don't worry if the same clothes are worn repeatedly, so long as they're clean.
