Iggy Pop's leathery torso. The hide of a true rock 'n' roll reptile! It's been through a lot.

Bowie's different coloured eyes (one permanently dilated). Handy for that mysterious, otherwordly, charismatic persona he developed.

You know that's going to come with some serious wailing ..... unless Alison Krauss is in the room.

Morrissey’s quiff

The ravages of age and the natural processes of erosion may have reduced it to a nub. In its prime, Morrissey’s gravity-defying hairstyle was the tonsorial equivalent of one of those overhanging cliffs that Wild E Coyote always ended-up plunging off in Road Runner cartoons.

Affording spectacular views across Manchester, the quiff was the perfect vantage point for an aspiring song-writer to take-in the world. As fantastic as The Smiths were, they would have no-doubt ascended to dizzy new heights, had Morrissey been able to scale the summit of his own hairstyle and breathe the rarefied air above his arched eyebrow.

and his wee pair of short trousers.
James Dean Bradfield - never seen him play without a white Gibson guitar. A nod to Sex Pistol Steve Jones I believe.
Johnny Fingers - pyjama wearing piano playing Boomtown Rat
Slash's top hat
Chrissie Hynde's wonderful unchanged hair style.

Henry Rollin’s ‘Search & Destroy’ back tattoo

As seen here

An anthropomorphic sun, the humanoid face squatting at its centre compressed and distorted, as if subject to immense pressure. A fitting tattoo for Rollins, who seems to thrive in a climate of adversity and who would happily lift huge weights under the punishing gravity of Jupiter if such a thing were possible. Of course, a real hard man wouldn’t have abbreviated the ‘and’.

Andrew Eldritch’s shades

What lies behind The Sisters of Mercy frontman’s dark glasses has long been a matter for speculation and raised expectations. One theory is that Eldritch replaced his eyes with cobwebs woven from fibre-optic spider silk, the resident spiders at their centre wired directly into his visual cortex – Something that would satisfy the Sisters’ Goth and Cyberpunk credentials.

If it’s just a normal pair of eyes then it would probably be better for all concerned if he grafted his shades to his face and preserved the mystery.

Ron's Hitleresque 70's style still the best.
