Changing regular clothes to nursing clothes...

So I have spent a long time gathering up my wardrobe via 2nd hand & consignment shopping.

I’m hoping to be able to breastfeed, but I don’t know how to do that with my wardrobe, since it’s mostly dresses... I was thinking that I would have to get some heavy duty snaps and some ribbons, and tailoring my dresses to unsnap at the shoulders? Or one shoulder (and if they’re feeding at the other breast I can use the widened neck hole to pull down the other side... maybe regularly wear nursing tanks underneath?)

What did y’all do when you were nursing/pumping?
