Answered by Ustadha Shazia Ahmad
Is it permissible to wear clothes made of pigskin or dog (canine) leather? Is it allowed to sell clothes or articles made of dogs or pigs? Is it allowed to pray with clothes made of dog or pork in the Shafi’i school?
Thank you for your question.
In the Shafi’i school, dogs, pigs, and their offspring are considered major filth. The hides of dogs or swine cannot be purified by tanning. [Keller, Reliance of the Traveler]
In summary, it is not permissible to wear in prayer, or outside of the prayer, any article of clothing made from dogs or pigs. It is likewise not permissible to sell such items because they are considered filth.

Purity and Judging Pigskin
Praying with a pig-leather wallet, do I have to make up such prayers?
May Allah give you the best of this world and the next.
