I was more commenting on the facts the wedding dress was several multiples more expensive then the suit. I’ve watched Say Yes to the Dress more times then I care to mention. It is, as you say, easy to spend more than $4,500 on a wedding dress. Kleinfelts has racks of them north of that price. Personally I coukd never see spending 5 figures on a wedding dress but for some it fulfills a childhood dream. If so go for it.
Agreed on the far greater utility of the suit but I expect the purchase of a wedding suit rarely, if ever, is fraught with the emotion so frequently invested in buying a wedding dress.
