I bought the jeans without trying them on and without finding a size tag in them. The waist looked to be size "extra plenty;" and big enough to accommodate the low-hanging watermelon that is my belly.
Tried them on at home--success. Nay, perfection. Maybe a little on the loose side, but since I've still got 8 weeks to go, that's a good problem to have.
Then, as I took off the blessed garment, I found that size tag. HA.
Is it fine to be a size 14? Well duh. Of course it is. But is it a shock to be a pre-pregnancy size of about 8, then to be wearing not only a size 14, but a maternity size 14, with plenty of weeks to go? YES, IT IS A SHOCK.
Maternity clothes/sizes are basically a crapshoot, so I'm issuing a new formula for determining your numerical maternity size, at least for Old Navy.
Take your pre-pregnancy size: 8
Add your trimester: 3
Add which number this baby is in your lineup: 3
