Nice Suit
Color: Deep Grey, Size: XX-Large, Color: Deep Grey, Size: XX-Large
Great quality for the price. Purchased during a flash sale. Comes with a bowtie and crown pin. My husband is 6'3 and 215lbs. This is a slim fit and the pants fit well without a belt. He normally wears a 36×34 and this suit was an XXL. He has big biceps and the jacket fits well in a relaxed state, but it's a bit tight when he lifted his arms or flexed.
