Fossil makes a quality bag for the money but the leather is not top end (don't get me wrong, it's nice!) and the treatment to make the leather and dye it isn't top end as well. But high end prices do not necessarily guarantee high end leathers or manufacturing.
Making leather is an extremely expensive endeavor, even before dyeing it, which is another expensive procedure (whether to drum dye or not, etc.) Buying leather handbags from manufacturers you absolutely trust is imperative. But generally the less expensive the leather brand the less they've done to ensure the quality of the leather.
I love leather bags and coats. I bought a Denim & Co. Moto jacket in black lamb leather last year and wore it one season I just got it out for this year and discovered that the black dye around the top of the collar has actually rubbed off! It cost about $170 and I knew when I purchased it that it wasn't high end.... but I also didn't expect the leather dye to not be secure!! Now I know..... with all that means.....
