BITSEACOCO Mens Gothic Medieval Tailcoat Jacket, Steampunk Vintage Victorian Frock High Collar Coat

Does the vest have pockets?

Would this work for an anatole cosplay from natasha, pierre, and the great comet of 1812?

What "high quality" material is actually used?

My shirt size is an 18/33. what size would be recommended for this? part of me wants to think it's a large, but i want to be sure. thanks!
