Definitely worth the buy
Size: Large, Color: Grey
The size large fits my fiance great. The vest and jacket are perfect size however the pants are bit snug and have to have the button moved in order for them to be buttond besides the button they are perfect. However I wish it came with the bow tie. The jackets button was sewn on to loosely so I will have to have that fixed as well but for such a decent price this suit is worth it. The qualof material is there. Just need to fix a few buttons.
