Great quality and price
Size: 44W x 29L, Color: Lieutenant
Very nice and great price. We only returned them because they weren’t the color or fit my husband was looking for. They were a gift so I based the purchase off his description. The jeans were exactly as described by the seller.

Good jeans
Size: 44W x 30L, Color: Lieutenant
Nice fit. Looks dressy enough for work or play. Comfortable enough, a little stiff fabric though. Holding up nicely to use and washing.

Comfot and fit
Size: 48W x 29L, Color: True Blue
Husband said very comfortable and fit great. Not too stretchy but a little bit. Plenty of give so tearing shouldn't be an issue. Soft and great quality.

What a beautiful coat
Size: XX-Large, Color: Navy Blue
I bought this coat to wear on valentines day and I had major doubts about it. But upon receiving the article I fell in love with it. The material it is made from is indeed high quality and the fit is damn near perfect. If your a bigger guy like myself, you may notice the arms are a bit long, but that's nothing a quick alteration can't fix. The coat is heavy and warm so perfect for those nice long walks with your partner at night. The color is exactly as it shows in the pictures and the look is absolutely spectacular. This is a great buy for a great price. I will be getting all colors in the near future.
