戴 drew hands lifting a mask or ornament onto the head — wearing as a deliberate ceremony. Chinese splits 'wear' by method: clothes are 穿 (pierced through by limbs), but hats, glasses, watches, and jewelry are 戴 — raised and placed.
戴 things carry status: 戴红领巾 the red scarf of schoolchildren, 戴戒指 the ring that announces engagement. 不共戴天 'cannot wear the same sky' is the idiom for irreconcilable enemies — the sky itself as something jointly worn.
Ceremonially lifting something onto your head — you WEAR it (hat, glasses, crown).
戴高乐 is de Gaulle's Chinese name — 'wears high happiness', possibly history's most flattering transliteration.
