Black work bag that can also be used for casual wear

[Ifyoubuildit]

Just that really. I need a new work bag as I'm working a 3 month contract but after that I need to use the bag for day to day casual wear.

It needs to be quite big (to fit iPad mini, notepad and other paraphernalia) and black. Willing to spend around £200 (it's for my birthday )

I normally buy this sort of thing at Russell and Bromley but they haven't got any I like.

Look at longchamp les pilages

This one is leather but over budget mobile.harrods.com/mt/www.harrods.com/product/le-pliage-cuir-small-handbag/longchamp/b12-0401-076-LGC-024

They do nylon and leather ones too under your budet but without the strap in plain colours

This one?
or this?
reduced Chloe

Thanks! I'm not sure if these tick the casual box too? What do you think?
