Wild Shape follows the normal polymorph rules.
When you cast a polymorph spell that changes you into a creature of the animal, dragon, elemental, magical beast, plant, or vermin type, all of your gear melds into your body. Items that provide constant bonuses and do not need to be activated continue to function while melded in this way (with the exception of armor and shield bonuses, which cease to function). Items that require activation cannot be used while you maintain that form. While in such a form, you cannot cast any spells that require material components (unless you have the Eschew Materials or Natural Spell feat), and can only cast spells with somatic or verbal components if the form you choose has the capability to make such movements or speak, such as a dragon.
Normally when you wildshape into an animal you don't have access to your spell components, you can't speak and you don't have appropriate limbs to perform somatic components.
However, the feat Natural Spell lets you cast spells as normal while under the effects of wildshape no matter what form you take.
A ring of eloquence plus the still feat is also a good option for us shapeshifting non-druids.

Druids are the premiere shapechanging spellcasters with natural spell, as it covers these.
Of course the arcanist has an exploit that functions as natural spell for but for all polymorph spells. That's nice too.
A polymorphic pouch might help with that.
