Clothing/shoes is probably the only reason to physically enter a store.
One big problem is for something specialized (an electronic component, for example) people might show up to the store to see if it is what they need (trying it out/ensuring it fits), then they leave and order it online for less money.
When a nearby mall had a tattoo shop open, and many of its retailers had morphed into food-centered places, it was clear brick-and-mortar retail was in for a rough time. The Kohls policy of accepting Amazon returns was smart - gave you a reason to at least show up in the store.

That is why we went to a Pendleton store for me to try on shirts and sweaters.
Even there, size was basically irrelevant. The western style shirt that fit me was a plain Jane/John large. Some larges off the same rack didn’t fit me.
The sweater my wife bought me was an extra large size. The other non Pendleton sweaters at our home that fit me, are large to to extra large.
One of our adult sons loves Uggs shoes, and each Christmas he buys my wife and I a new pair on line. They fit again this year. Last year’s inside Uggs become our outside go to the store shoes. The older ones become the work outside shoes.
