Pregnancy support belt

hi! i actually was using the OppO maternity belt during my second trimester and entering my 3rd trimester but i find it slightly lose as my pregnant belly is relatively smaller than average (i even got the smallest size). but it is actually a good support belt even though it was slightly big for me- i wore it to sleep/rest because doctor recommended to help with my posture! i did not have any itchiness or skin feeling hot while using it the whole day at work! something to consider!
