Bikini tops. Skin. Boobs. None of these things are shirts. The kicker here is, she HAS a shirt, and is just wearing it exclusively around her wrists.
This is from the 2000 X-Men premiere, in which Halle plays Storm and wore full-body full-coverage leather. She must have been aiming for the exact opposite clothing statement here, and by that standard I guess she nailed it? Surely Halle knows she doesn’t have to try this hard. As if any of us would ever forget, could ever forget, that she is Halle Freaking Berry, Divine Physical Specimen, Lightning Strike of the Gods. She could be wearing a four-person camping tent from the spring REI catalog and that would still be obvious.
