My granddaughter hates bundling up

My granddaughter lives with me because she goes to a private school that’s close to where I live. She’s usually really good about following my rules, but now that it’s getting cold again and I make her bundle up she always makes a fuss about it.
Today was a very cold day so when we went out to run errands I made my granddaughter dress warm. I had her wear snow pants, warm boots, two sweaters, a down jacket, and a long winter parka. I also made her wear mittens, a hat, a scarf, and her hoods up.
She got very upset that I made her dress warm, and she says she hates wearing her winter clothes to school. Does anyone know how to deal with something like this?
