Powder helps but will make you smell like powder.
Otherwise wear what you want but get it in a neutral color like heather grey or black.
And for when at home do try the powder and let that area air out as much as possible to keep the skin breakdown down to the minimum.
If you start to get ulcers/wounds there seek some help quick. Staff infections down there can be lethal or disfiguring. I almost lost my father-in-law to it about four years ago. The surgeon thought that he might have to amputate a leg and consult a gastric surgeon because it was creeping into his abdomen.
