mummies who're pumping at work, what are sort of office attire which facilitate dual pumping? dresses or separates? I bought some pro-breastfeeding dresses, only to find out I can't do dual pumping in them (bf = one breast at a time, while dual pumping = both breast at the same time)..

I've noticed that either dresses or separates work well, but they have to be button down types. It's easy access with buttons, I feel. It's a popular option with my colleagues too. At my old work place, we wore uniforms and those were button down tops as well and my then mommy colleagues never had any trouble pumping at work.
