💜
my 6’4” husband wore this to our wedding. it looked amazing on him 💜 everything fit pretty good except for the jacket part; that was a little big. it may fit someone who weighs a little more but my husband weighs about 165lbs. we had to tailor it a little bit. other than that, very beautiful suit.
