I'm looking for a bag that goes with most things in.my wardrobe. I am currently in the process of loosing weight and am trying to make do with the clothes I already have that fit and as a result have a rather odd colour mix 
I'm wearing lots of blue denim/navy/black/ brown and my current jacket is grey!
Is there a bag that will go with everything I wear? I'm hopeless at changing my bag depending on my outfit and as a result feel very un put together!
Was thinking maybe a nude kind of colour or grey or tan? Budget is as small as possible ideally under £40 but it must be on the roomy side as I have small dcs. Not too worried about longevity. TIA
