Dowdy people, or those who are perceived as lacking style or fashion sense, can be described in a variety of ways. Some synonyms include frumpy, unappealing, unfashionable, outdated, old-fashioned, dowager, and shabby. These words all suggest a lack of aesthetic appeal or a disregard for current trends. Other possible synonyms might include dull, drab, or unremarkable, emphasizing a general lack of interest or charm. However, it's important to note that fashion should not be the only measure of an individual's worth or personality. Labels like "dowdy" are often arbitrary and divisive, and it's important to embrace diversity and individuality in all forms.
