Does Alex notice her current form?

Yep!

Alex's fingers brushed against the rough bark of the tree as she steadied herself, her mind foggy and her thoughts scattered. She had been walking for what felt like hours, the world around her a blur. But as she bent down to pick up the book, something felt off. Her gaze dropped to her feet, and her breath hitched. They were bare, the dirt and leaves clinging to her skin. Slowly, her eyes traveled up her legs, and her heart skipped a beat. She was naked. The realization hit her like a wave, and she froze, her hand hovering over the book.

Alex's scream pierced the air, a raw, primal sound that sent shockwaves through the quiet suburban street. The man's head snapped towards her, his eyes widening in disbelief. His grip on the tattered clothes tightened involuntarily, the fabric crumpling in his clenched fists. For a moment, he forgot to breathe, his heart hammering against his ribs like a frantic drum. The squirrels, startled by the sudden noise, darted up the nearest tree, their high-pitched chirps filling the air as they fled. Birds took flight, their wings beating rapidly as they escaped the disturbance. The man's face paled, his lips parting slightly as if to speak, but no words came.
