'Kleidung' (clothing) is a collective noun and is almost always used only in the singular in German. There is no plural form 'Kleidungen'.
Im Winter braucht man warme Kleidung.
In winter, you need warm clothing.
Since 'Kleidung' (clothing) is an uncountable word, German uses 'das Kleidungsstück' (item of clothing; plural: 'die Kleidungsstücke') when you want to name or count individual pieces.
Nimm nicht so viele einzelne Kleidungsstücke mit in den Urlaub.
Don't take too many individual items of clothing with you on vacation.
The noun 'Kleidung' (clothing) is derived from the verb 'sich kleiden' (to dress oneself). The ending '-ung' turns the action of getting dressed into a noun.
Er kleidet sich immer sehr elegant.
He always dresses very elegantly.
To describe the type of clothing, 'Kleidung' is often combined with adjectives. Common examples are 'warme Kleidung' (warm clothing), 'sportliche Kleidung' (sporty clothing), or 'bequeme Kleidung' (comfortable clothing).
Für die Wanderung empfehle ich bequeme Kleidung und feste Schuhe.
For the hike, I recommend comfortable clothing and sturdy shoes.

Both words can refer to things worn on the body. „Kleidung“ means the clothes someone wears as a whole, while „Wäsche“ refers to the same or similar items in connection with washing. „Kleidung“ fits when talking generally about what someone wears; „Wäsche“ fits when washing or clean items are involved.
