sainsburys premium leggings

[jamtartandcustard]

so after all the fab reviews, and the fact that tu has 25% off at the moment, I'm just in the process of ordering some of the sainsburys premium leggings to wear post pregnancy. I was just wondering what they are like re: fit. do they have much stretch in the waist? i'm just trying to decide whether to order my normal pre-preg size (14) or whether to size up and go for the 16?
advice greatly appreciated

I'd personally plump for a 14. Failing that, order both a 14 and a 16 and return one. It's free click and collect if you spend £15.

Thank you for the heads up - I've just purchased two pairs of black and two pairs of navying leggings plus two tunics from Tu. Plus a pair of PJs for DS.
