Very bad choice. I relied on the description and comments and with measurements I ordered a size Medium. It reaches just below the chest, where it fits but unfortunately the elastic is not suitable for pregnancy. The fabric is extremely transparent. Everything is visible from the inside. Unfortunately, such poor quality fabric that is transparent forced me to return it.

Obviously it's not the epitome of style, but it's very comfortable with nice fabric.
I have a waist circumference of 105cm and a hip circumference of 61cm (36th week), and I wear the Small size and it's just right.
It's a shame I didn't think to get it earlier than the 9th month, it's very convenient for exercise, household chores, walking, etc.
It's great for the summer when we sweat, as it doesn't rub and cause chafing between the thighs. You can also wear it under a dress to avoid friction on the inner thighs.
