What you suppose an alicorn's hair feels like?

[Bendy 1,819]

What you suppose an alicorn's hair feels like? (or mane or whatever) Let's say Luna or Celestia. You happen a have very a highly paid, privileged position of the Royal Petter as the only Human in Equestria. In where you have the job of petting pony princesses.

Definitely would be very silky, smooth and great for lying in!

Some sort of gooey substance. Either that or plasma, and nopony wants to touch plasma.

I thought about touching Celestia’s mane and immediately remembered this;

[Props Valroa 25,969]

I imagine it feels smooth, silky, and wavey.

[Clawdeen 12,109]

I’d assume it’s very smooth and soft

[Sazama Ichida 2,352]

It likely feels ethereal, soft, silky, and smooth.

[Gaines 1,105]

I always thought my hoof would just phase right through them

Well, Pip could pull Luna's hair in Luna Eclipsed and that short with Rarity wanting moving hair suggested that it really is 'just' hair that's enhanced with magic; it became still when the Princesses gave up their power to Twilight for safekeeping, and Twilight's hair started to move when she used it to move the sun/moon.

Same as everyone else, really soft and silky, but imagine that super silky way that constantly seems to move because of the sheer glossiness of it. Or imagine the patch of fur you can find under a cat or kitten's ear; that super soft fur! If you've ever touched the fluffy buds of a pussy willow, you know how soft it is

When they're powered up it's probably just like warm and misty. Otherwise just like normal hair/fur.
