Hello,
I don't know why I didn't think of Mumsnet when I began my search but I finally realised.
I'm looked for a pretty and structured daily hand bag:
That can be zipped at the top
A colour that suits all, can be black
Can fit a MacBook Air and also other belongings without it getting tight
Wouldn't hurt if it can be cross body and/or long enough to be on the shoulder too (don't know how to explain this)
I have searched high and low and can't find anything that fits into my category 
Thank you in advance!
