What Do Those in the Islamic Paradises Wear?

S 18:31 Those, theirs are Jannat of ‘Adn, rivers running beneath them. They are adorned therein with bracelets of gold and wear green garments of sundus and istabraq, reclining therein on the couches. Excellent was the reward and good as a support.

S 22:23 Allah admits those who have believed and have done the righteous deeds to jannat, rivers running beneath them. They are adorned with bracelets of gold and pearls and their garment therein is silk.

S 35:33 Jannat of ‘Adn, they enter them. They are adorned therein with bracelets of gold, and pearls, and their garment is silk.

S 44:53 Wearing sundus and istabraq facing one another.

S 76:12 And he has recompensed them because they were patient with a jannah and silk.

S 76:21 Upon them are garments of green sundus and istabraq and they were adorned with bracelets of silver and their lord gave them to drink a pure drink.

So in the hereafter Muslims wear either a (green) silk garment or a number of them and either a gold or a silver bracelet, depending upon the verse.

The denizens of the Jannah, or jannahs, don't sweat but do they shed skin flakes? If there is no dirt up there, why might they have three or more garments and are these garments eternal?

A‘isha told that God’s messenger was questioned about Waraqa and Khadija said to him, “He believed on you, but died before you appeared as a prophet.” God’s messenger then said:

“I was shown him in a dream wearing white clothes, and if he had been one of the inhabitants of hell he would have been wearing different clothing.” Ahmad and Tirmidhi transmitted it.

Now, if the denizens of the one or more paradises wear green clothing, why might Waraqah be wearing white? And why might the denizens of hell be wearing clothes and are their clothes fireproof?
