I can't say that it would be for the rest of my life, but I'd pick another Jerome Dreyfuss bag in either goatskin or snake skin. I just bought the Billy M in goatskin and have been using it for two weeks straight. It's the best. I can't put it down although I have tons of handbags.
As for all of the big-named designers like Chanel, Vuitton, etc...I like them, but have had them for decades. But, Jerome Dreyfuss bags are great, down-to-earth, and highly functional bags and the inner flashlight, that they come with, is so functional.
