Totemic Skald Wild Shape Mask of Giants magic item question

[Jeff Clem]

Totemic Skald has the ability to wild shape one small or medium animal.

Wild Shape (Su)

At 5th level, a totemic skald gains the ability to wild shape into the form of a Small or Medium version of his totem animal, as the druid class feature. His effective druid level for this ability is equal to his skald level – 1. He can use this ability twice per day at 11th level, and three times per day at 17th level. This doesn't allow the skald to assume other forms, such as elementals, plants, or other kinds of animals.

Mask of Giants

This wooden mask depicts a leering humanoid with an oversized nose and ears. If the wearer has the wild shape class feature, the mask allows her to use wild shape to take the form of a humanoid with the giant subtype. The forms allowed by a lesser mask of giants are ogre, troll, fire giant, frost giant, or stone giant. If the form has any of the following abilities, the wearer gains the listed ability: darkvision 60 feet, low-light vision, scent. In giant form, the wearer gains a +4 size bonus to Strength, a –2 penalty to Dexterity, and a +1 natural armor bonus.

My question is can a Totemic Skald use a Mask of Giants to wild shape in to giant subtype like the item states even the wild shape restriction.

Yes, a druid can't normally wildshape into a giant either, it's the item letting you do it.

Item requires Wild Shape class feature, you've got it.

[MurphysParadox]

The Totemic Skald has Wild Shape just like a Druid*. (* - not valid for certain forms). It is written this way so you can just turn to the druid section for the rules, as opposed to reprinting it all in the skald archetype. But, for all purposes of "do you have Wild Shape?" the answer is yes.

The Mask lets anyone who has Wild Shape turn into giants.

So basic Wild Shape is limited by Totemic Skald power. Then the mask adds to Wild Shape. Since the mask is letting the skald turn into a giant, not the basic druid Wild Shape ability, it is fine.
