Great pirate jacket

Was purchased for a costume and is nicely done. Material is soft and well sown. Looks good one.

It looks ok??
Size: XX-Large, Color: Black
This is not much of a jacket. It's relatively thin and doesn't block a breeze... That being said, the fit is accurate with the size chart. It's not very expensive, but feels like it should be about half this price

Great cosplay jacket
Size: Small, Color: Black, Size: Small, Color: Black
I bought a jacket similar to this about 4 years ago and I absolutely hated it. It was cheaply made and so shiny it could blind a nighttime driver. I needed another one because my son out grew the old one. I hated having to buy what I thought would be another cheap jacket but when it came in, I was shocked. Apparently, I bought from a different maker because this jacket was perfect. Well made. Easily ironed out the wrinkles. This turned out to be the perfect jacket for my son. He loved it. I really love it. Very happy with this purchase. Hopefully, I do not have to buy another one but if I do, it will be this brand. I have saved it in my list just in case I do need to order another. It is so nice. Extremely happy with my purchase.

Coat is very nice - - I didn't expect it to be as nice as it is!
Size: X-Large, Color: Black
This coat arrived promptly, and I am very pleased with it. Very wrinkled, but it ironed up real nice. My husband is usually in between a Size L and an XL. I ordered an L first and it was too tight, so I returned it and ordered an XL and it was too big, so I would say the sizing is spot-on. I was able to take up the sides enough that it now looks good on him. The fabric and construction seem sturdy. He is wearing it to an Edgar Allan Poe function, and I think he will look fabulous.
