YIM Jeans sit under your belly and are constructed with an adjustable elastic inside the waistband which, once in the correct position, is inserted back into the wasitband so it does not hang loose or irritate your bare skin!
The soft stretch denim allows the jeans to grow with you, therefore keeping you comfortable for the entire 40 weeks and until you can fit back into your old jeans.
As the denim is stretch, it will give with wear, so make sure you try the size below your pre-pregnancy size - the firmer the fit, the better is recommended at the time of purchase!!
