So on brand bloomers, from looking at the pictures, it looks to me like at the waistband they have two compartments (might not be a good word but I can't think of anything better) with elastic running through. Some girl on another website was claiming that they actually have three and there is no elastic in the middle one. She said that this is the best way to sew bloomers. But that just sounds really weird to me.
Does that have any truth behind it? Or is it what it looks like and there's just 2?
