How early do you order grooms attire?

We booked FH's rental about two months before our wedding. One of the groomsmen has booked theirs, the other is still working on it (we're now almost a month away).

As for the bridesmaids, usually 3-4 months before the wedding is long enough for MOST dresses to come in. Sometimes specific styles may take longer, but usually that's plenty of time.

We are going to look at tuxes for my FH and groomsman in March, so about 6 months out. After we do that we are going to let the groomsmen know that they can book their rentals as well. For bridesmaid, I already gave them the information as to where to order from. They will be getting dresses from Azazie. I think they all plan to order in June since production time is fairly quick. The only thing I am or my FH is buying for the groomsmen are ties because I want the color to match the color of the dresses I picked for my bridesmaids. Otherwise they will be responsible for paying for their tuxes. The same goes for my bridesmaids, I am paying for their hair to help them out.

My fiance is wearing a custom suite which we already ordered (we are 2.5 months from wedding). They recommend we come 3 weeks before wedding for the groomsmen's rentals.

1. My husband and I started looking for suites months out. We didn't plan on purchasing them, we planned on renting them. We went into 3 stores and did 3 online free try ons. He picked 2 months out & told his groomsmen then. My husband did purchase his button down white shirt & have it altered, alterations took about a week. We also purchased all the ties & pocket squares, we did that about 2 months out.

2. I told my bridesmaids 14 months out about their dresses. I picked Azazie and gave them a color, fabric & length so they could pick their own dress in their own price range. Since they had such far notice, several took advantage of things like black friday 15% off and other sales.
