The sentence type is complex sentence.

Explanation: A complex sentence is made up of an independent clause and one or more dependent clauses. While an independent clause can stand alone as a sentence, a dependent clause cannot stand by itself because it does not express a full idea. Moreover, unlike an independent clause, a dependent clause is always introduced by a subordinating conjunction. The sentence provided is a complex sentence because it contains a dependent clause ("While I was cleaning out my closet the other day") and an independent clause ("I came across my favorite pair of childhood shoes: purple and black jellies with gold buckles"). The dependent clause, which is not expressing a complete idea, has been introduced by the subordinating conjunction "while".
