👗👔 服 clothes (fuku) + 装 dress up (sou) = attire
服 fuku is the clothes kanji in 洋服 (Western clothes). 装 sou means to dress or equip, as in 衣装 (costume) and 変装 (disguise). Put clothes together with dressing up and you get attire, the whole outfit someone wears.
服 — 月 (moon/flesh) + 𠬝 (kneeling figure with hand)
Originally depicted a hand subduing a kneeling person beside a boat (later simplified to 月), suggesting submission or service. The meaning extended from 'submit/serve' to 'clothing' (what one wears in service) and 'to take' as in medicine. The phonetic role of 𠬝 helps fix the reading fú.
装 — clothes 衣 + strong 壮 (phonetic)
装 is a semantic-phonetic compound. The bottom 衣 ('clothes') gives the meaning, since the original sense was packing or dressing—putting clothes or goods into a bundle. The top 壮 supplies the sound. Meanings extended from 'to dress/attire' to 'to load, install, pretend'.
