Skins bought from the market are character bound ?

[Paolini]

Or class bound ? Omen skin bought with gold can it be shared between Berserker/Paladin ?

Pretty sure they are roster bound and locked to the main class types. For instance, I believe buying a skin for a Bard would also work on a Sorceress too since it says they are Mage specific and roster bound.

roaster bound but you can equip only on one char

[Irot Noot]

I just tested sending the head piece skin from the Omen set from my Sorceress to my Bard via the roster bank, no problems. Worked fine. The items are indeed roster bound, but also set to the main class. In my case Mage is both Bards and Sorceresses. Mix n match if you will. You 'should' be able to do what you are suggesting if the same rules hold true for the Warrior classes.

You can share them between roster characters freely but its class locked based on the first class you give it to.

In the large scheme of things I can't say I'm very mad about this.
