I figure I'm going to have excess skin and lots of wobbles post baby, so I want one of these.

I just bought one off ebay (a whole $10, yay) that was pegged as 23-33 inch waist. I thought this would be fine, but it arrived yesterday and my partner tried it on and it was loose - and he's 33 inch waist! I'm way smaller than him so its going to be useless on me.

Has anyone had one of these? If you would normally be a 26-28 inch waist, what size do you need to get? The smallest size they had listed on ebay still goes from 20-27 inches which kind of makes me think its going to be loose at 27 inches.

Is there something better than the elastic ones you can use to hold the wobbles in under your clothes? Muffin tops aren't a good look and with the last baby I had a muffin top that was just skin so I had to watch that I didn't wear tops that were too short or it would come out and say hi
