Explanation:
An adverb is a word that modifies an adjective, a verb, or another adverb. In the sentence, we have the adverb of time "today".
An adjective is a word that modifies a noun. In the sentence, we have two adjectives. "Fashion" is modifying the noun "show", and "sports" is modifying the noun "clothes".
An article is a word that defines a noun, making it specific or not specific. In the sentence, we have the article "a", making the noun "show" unspecific.
Prepositional phrases consist of prepositions and their complements. In this case, we have "of sports clothes", the preposition being "of", the complement being "sports clothes".
Finally, a pronoun is a word that substitutes a noun or noun phrase in a sentence. In this case, we have the subject pronoun "they". It is unclear to whom this pronoun refers, but the speaker and his/her interlocutor would certainly know in the context of the conversation.
