Typical costs:

Tuxedo or suit costs vary, depending on whether the groom rents or buys. On the low end, tuxedo rentals start at about $50 to $100 for rental of a basic wool tuxedo and vest.
In the mid-range, groomsmen can buy a nice suit or tuxedo for between$300 and $800.
And, on the high end, it costs about $800 to $1,500 and up to purchase a quality designer wool tuxedo or suit.

What should be included:

Tuxedo rental includes professional measurement and fitting, as well as pressing, cleaning and overnight use of the tuxedo. Sometimes, as a special offer, a vest will be included free.
With the purchase of a suit, some retailers will hem the pants or shorten the sleeves for free. It is a good idea to ask ahead of time if any alterations are included.

Additional costs:

For tuxedo rental, vests, ties and shoes and shirt typically cost extra. And, of course, if you buy a suit, you will need to buy a shirt, tie and cufflinks, too, which can cost $100 or more.
Alterations, if not included with the suit, can tack on $30 to $100 or more, depending on how much time and skill they require.

Discounts:

On websites of formalwear rental companies, it is often possible to find coupons for rentals for groomsmen, which sometimes include a free use of a vest, or other accessory. Shops compete for business, so it is a good idea to call around and ask about price breaks.

Shopping for a groomsman's suit or tuxedo:

Norman's Tux provides a guide that shows exactly how groomsmen's attire can match or differ from the groom's, depending on the formality level of the wedding.
Even a rented tuxedo needs to be tailored to fit, and it is important to get that done well before the wedding day to avoid adding to the couple's stress.
For groomsmen who live in different cities, renting or purchasing matching ensembles can be the most difficult part. For that reason, a chain store might be the most convenient option to coordinate their attire. For rentals, look at chains such as After Hours Formalwear or The Men's Wearhouse.
If going the informal route, with each groomsman purchasing a similar-colored suit and tie, groomsmen should communicate with the couple and each other to be clear they have an understanding of which shades of colors are acceptable. If groomsmen still wish to purchase matching ties, they should consider an online retailer, with examples such as JCrew.com, BananaRepublic.com and Nordstrom.com. Tie color can be coordinated with bridesmaids' dresses by requesting a swatch of the dress fabric.
To buy a suit, check chain department stores such as Nordstrom or Macy's or men's stores such as The Men's Wearhouse.
