Honestly, other than price point, I don't understand the distinction between Designer and Contemporary.
I've looked at some very expensive handbags at Neiman Marcus and Saks and just didn't get it. I was hoping there was some voodoo magic with the, oh let's say, over a grand bags. A lot of them are really trendy and would look outdated in a short amount of time.
I did own a Tod's. Evidently that is a designer bag. It was very well made and that one made more sense.
I think the Coach Legacy line 65th Anniversary leathers and the Dooney Florentine leathers have outstanding workmanship and materials. Especially for the price point.
But, I believe if one particular bag (Designer, Contemporary, handmade by elves, etc.) gives you New Purse High for a long, long time, I say go for it.
