I tend to wear pants and skirts that are nearly falling off me because any waistband, even elastic sends my gut into severe cramps...and sometimes a full blown bowel partial obstruction from the knotted gut muscles....which is only relieved by a BM.  If you happen to be constipated as well and the BM is delayed, then I have to weather a long period of horrible pain.  If I am not constipated then the urgency is so bad, sometimes I don't make it in time to that place that can finally flush it all away.

All that from wearing clothes!
