Currently just underwear, but earlier I was wearing bikini bottoms as an underlayer with a sanitary pad on it, and underwear on top of that. It actually held up pretty well as long as I didn't empty my whole bladder
I am wearing a tena small I am going to bed in a few minutes so I will change into a heavier weight diaper that is going to handle over night wetting since I mostly wet during the night just leak enough during the day to need to wear diapers but I don't mind it at all it's just a part of who I am now
