I always suggest getting the smaller size. Corsets tend to make you eat smaller meals.
But I know there are times where you take off your corset to eat.
I do it all the time.
So theres the thing…
If you’re in the process of losing weight then go for the smaller corset.
It may take some time to close, but it will fit you for a longer time.
If your weight fluctuates or is increasing, then get the larger size corset.
You may need to eventually get a smaller corset faster, but at least you wont be rushing your body, and you can slowly close it.
Another thing to take into consideration is if you like to close your corset for the aesthetics, get the larger corset.
If you don’t mind a gap in the back, choose the smaller one.
