Love my Neverfull MM!!
It took me a while to decide whether I wanted to splurge on a $600+ bag or not, but I'm glad I did... it is the perfect size and style to carry everyday. I am a therapist so I work an irregular schedule... some days I'm at my office, some I'm running errands, some I'm out shopping or meeting a friend for lunch... and this bag definitely works for all those things!
I really like the thinner straps... I have narrow shoulders and they give me no problems at all staying on or feeling comfortable. The bag is deep and roomy enough to hold everything I need (wallet, phone, keys, cosmetic kit, sunglass case, water bottle, files for work plus a sweater), and the sides cinch up a lot so even in the city, I'm not overly worried about people reaching in, or things falling out.
Definitely a versatile bag... I'm so glad to have found something casual and comfy that still looks polished and professional!
