Once your belly starts popping out, it's tough to wear your pre-pregnancy jeans because you'll have to wear them lower, under your belly and they may fall or simply not button up at all. However, there are some things you can try that will help you wear your pre-pregnancy jeans just a little bit longer.
BellaBand Organic - BellaBand can be worn over your pre-pregnancy jeans to help hold them up, even unbuttoned. The band can also be worn to hold up too loose maternity jeans and to help you wear your pre-pregnancy jeans again after you give birth.

Invisible suspenders clip securely to the waistband of your jeans, or other garments and will prevent them from sliding down. Best of all these are worn under your clothes.
