Hailey Baldwin Fights Warm Bev Hills Weather with All Leather Outfit

Hailey Baldwin is hell-bent on leather ... even in hellish-like weather.

The model was seen rocking an almost fully leather ensemble Tuesday in Bev Hills, where temps are supposed to reach the upper 80s.

That's not a problem for Hailey, apparently -- she was decked out in leather Bermuda shorts and a leather jacket ... plus heels, of course. We're told the look is from WHYTE STUDIO SS18.

On a positive note, she did manage to show some skin even under all the cow ... always a good thing, if you ask us.

Looking fine at 86 degrees ... no sweat.
