For my wedding, my ring bearers ordered grey pants and dress shirts from LPC. We had consistent problems working with the company.
The sizing chart is not true to the children's size, and we were not provided with return information. Worse, though, is that one family never received the pants that they ordered a month in advance. The mother had to consistently call the company for days to try to figure out where the pants were and was given inaccurate tracking information and excuses ("it is father's day weekend" "the carrier is losing many items"). She was assured it would arrive a certain date and it did not over and over again. We did not receive a refund. I would never recommend working with them again.
