Wedding dress experts advise to start working on groom’s wedding outfit about 3 months before the wedding. This will also save you money because last-minute orders always cost extra, you’ll save a lot buying and even custom-making your wedding clothing and accessories in advance. When you have time, you can look for the right garment for days, ask around, find a perfect suit from the rack instead of paying extra for tailored attire, etc. Besides, you’ll have enough time to make any adjustments if they’re needed.
