I always wear lingerie under my male clothes and as long as your sensible I have been getting away with it for years . I wear French nickers , full length slips ,stockings and the odd bras when I am wearing a jumper. If you wear a nylon shirt you have to be careful that your bra straps don't show through ? If I want to be spotted I open up my top,buttons on my shirt which lets people see my lacy bra slip ? It's a great feeling being in a room full of guys and knowing that you are wearing sexy lingerie under your male gear
