What are the chances that someone will find out you are under dressing at work? Unless you have a heart attack at work the chances are nil. it is not like management does an surprise underwear check.
There have been many threads/postings of bra straps and adjusters being discovered by women. Stay with the panties if you must.
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
