4XL or Size 4 Maternity??

The person who made the genius decision to put the big lady section and the maternity section together in every store is a skinny, childless bitch. What woman wants to discover that her everyday size is bigger than a 8 month pregnant woman? And I held up a size 18W pair of pants today unknowingly, and thought eh, maybe. Not what I needed since I was shopping because I only have 2 pair of pants that actually fit anymore! Holy hormones!
