I bought this after not being satisfied with a band bought at Target. Friends and reviews recommended Bella Band, and I see why.
The band hold firmly, but not uncomfortably. A size 10 prepregnancy, I bought the size 2 and it works great. I already use it because of lots of bloating, some weight gain and because I already started out with some extra weight around my midsection.
The band has a newly-added band of some kind of silicone or plastic that grips your jeans very well.
