We are having the groomsmen order suits from Men's Warehouse. We are only requiring the pants, shirt, and vest but are going to have a matching jacket available if they want a 3 piece suit. When do they need to order by for a June 2015 wedding? We haven't gone to the store yet to pick it out and I know that needs to be done first. Just not sure when to ask them to have them ordered by. Also, what is a reasonable amount to ask them to spend? The BM dresses are around $175 with taxes and shipping.
