My husband, both groomsmen, and my dad all purchased suites from Studio Suit for our October 1 wedding in the Bahamas.  Everything worked out great!  I will say this though: some did have to get alterations done, but mostly because they didn't follow the measurement directions provided on the site.  When you're measuring, wear a suit that you own that fits you well: that's what my dad did, and his came out the best of all of them.
