I don't have the Julia tote either but I have the Patent Leather Charm Tote that has narrow straps...I have not had a problem with the straps digging into my shoulders and when I use that bag, I tend to carry more than my usual load...though I must say I don't carry it for very long distances, i.e. commuting. I love my charm tote (Apple green)I don't have it but worried about that...thus haven't purchased one yet...I do like the simplicity of it and I am a tote girl.
Strap durability is my biggest concern with this bag. I snagged one last week at Macy's during the One Day Sale. When I think of totes I think of something that can handle (pun intended) being fully loaded with general office stuff such as files, laptop, things like that to some degree. I love the styling and the leather, but I'll have to keep load capacity in mind.You can;t carry too much in it. I had my iPad in there as extra weight and the strap broke on my cherry one. I exchanged it out for a different bag.
