Dressed in a Tent 

A phrase that describes clothing, usually of a woman, that is so loose or baggy that one can't determine the shape or outline of her body. The phrase can describe clothing that is designed to be loose or poorly-fitting clothes that are many sizes too large. This type of clothing is often worn by people who like to dress conservatively, people who are concerned about their weight, and the elderly.

"I don't care if she's curvy, she shouldn't have to dress in a tent to be respected at the office!"
"Did you see Brent the other day? He's recently lost a lot of weight, and he was wearing his old clothes at the store. He was practically dressed in a tent!"
"My grandma was dressed in a tent at my brother's wedding. It's so sad that no one designs nice-looking clothes for the elderly."
