Jacket drapes nicely without feeling stiff or overly formal in an uncomfortable way.
Three pieces coordinated means one less thing to worry about getting right.
My husband wore this to our nephew's wedding and got compliments all night. The tailoring actually lets him move around naturally, which he appreciated during the reception.
I was skeptical about ordering formal wear online, but everything arrived in perfect condition and actually fits better than expected. The gray option looked classy without being too serious.
Took a chance on the navy for a gala downtown, and honestly the structured lines made me feel confident walking in. The return window meant I could order my regular size without stress, which was nice.
