I don't work in the fashion industry either (I'm a teacher) but I still buy what I love and what works for me. You don't have to work in the fashion industry to buy new designs.
Why don't you use the Antigonas?
Having both Antigona and computer bag at the same time is too much for me. So I use small crossed body bag and computer bag. At the weekend I could use it but I often go for something more convenient such as Speedy B or Turrenne Mm
