One piece was true to size and the other wasn’t
Color: Brilliant Black, Size: XX-Large
Looked nice and perhaps decent quality for the price, but one piece fit while the other didn’t, like I forgot which, but either the jacket fit, but the pants were too big or small or vice versa . Had to return it.

Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.
