Dizens is a verb that means to dress someone up in a fancy or showy way. Antonyms for this word would include "undress," "disrobe," "strip," "unadorn," "neglect," "deface," and "dishevel." When you undress someone, you remove their clothing, while dizens puts clothing on them. Disrobing is similar but has the added sense of removing a more formal type of clothing, such as a suit or gown. Stripping someone implies removing all clothing, and therefore the opposite of dizens. If you unadorn something, you remove its decorations or ornaments, while neglect suggests failing to pay attention to it. Defacing something usually involves damaging or spoiling its appearance, and dishevelling something suggests making it look untidy.
