Frumpy
"Frumpy" is an adjective used to describe a style of clothing or appearance that is considered outdated, unfashionable, or lacking in elegance. It often refers to outfits that are baggy, ill-fitting, or overly conservative, which can make a person look older or less polished than they might prefer.
The term can apply to both men and women, but it is more commonly associated with women's fashion. People may use "frumpy" to describe someone who prioritizes comfort over style, often wearing clothes that do not enhance their figure or reflect current trends, such as sweatpants or oversized sweaters.
