I am not a very big person and always a 10 in undies but these are too small so I do suggest doing up a size. They are comfy and last ages.

Comfy undies but the sizing is a little off. I would suggest going up a size from your normal for these undies. Convenient finding in supermarket

I bought a pack of these to wear whilst pregnant as i found some maternity ones didn’t fit quite right, they are comfortable and don’t ride up but can leave a little bit of panty line when worn with leggings.
