"Frump" refers to a style or appearance that is considered outdated, unfashionable, or lacking in modern appeal. It often describes clothing or personal grooming that does not align with current trends, making the individual appear old-fashioned or unkempt. This term can apply to both men and women, though it is more commonly associated with women's fashion. The concept of being frumpy can also extend to attitudes and behaviors that seem out of touch with contemporary culture. People labeled as frumpy may be perceived as not keeping up with societal norms or expectations, which can affect their social interactions and self-image.
