A participle is a term for a non-finite verb form, which can have different functions within a sentence. As there are two types of participles: <em>present participles</em> (which end in -ing) and<em> past participles</em> (-ed, -d, -t, -en, or -n), "dressed" is a past participle. It acts as an adjective in this sentence, as it describes and provides certain information about the noun "bride."
