I just discovered Dimoni. Found it at TJMaxx. I want to address the original question, albeit have only perused some of the other posts.
To my knowledge you're not going to find high fashion euro-style leathers made in the USA (for obvious reasons, I do not include western-style saddlery and/or native american artwork, inarguably fine in their own right but whole separate 'genres' for sure). Born in the saddlery trade, Italy, France, Germany hold title for doing the best of leathers. There may be up-and-comers (Brazil included), but the finest of artisans with lineage to generations have a mindset/commitment to quality unheard of elsewhere. If you know fine saddlery you know what I mean. Cost of production in mainland U.S. is only but one of the reasons europe hails king in fine leather fabrication. Discounters (TJMaxx being the largest U.S. importer) buy up unsold lots of merchandise from select designers -- I'm sure there are brokers involved; we have to rely on their buyers' good instinct to make sure each one's legit. It helps a whole lot for us as consumers to Google designers by name and do any research we can before we commit to purchase. TLC and proper storage will make a good bag last a lifetime.
