Relaxin Frank, nice first post you made! My wife too knows how much I like to wear pantyhose. We are exactly the same size from the waist down, so all her pants, pantyhose, leggings, and panties fit me. Like you and your wife do, we both love to wear pantyhose or tights around the house together. It turns us both on, and we often start groping each other, which usually leads to hot sex.
One time when we went to Mardi Gras in New Orleans, my wife secretly brought along a costume for me to wear. Before leaving our motel room Tuesday morning, she encouraged me to drink a lot more than I normally would have, even for Mardi Gras. Then she brought out my Mardi Gras costume. She handed me a pair of her sheerest, black pantyhose. I couldn't resist pulling them on. Over that I pulled on a pair of high, stretchy, black boots that she bought for me. She then pulled out one of her stretchy, black thong panties. I stepped into them, and she pulled them up tight between my butt cheeks. That was it for my costume from the waist down. I loved it, but my wife insisted that I wear it to Mardi Gras! I strongly objected, but then she gave me a couple more drinks while I watched her strip and put on her costume. It was just like mine from the waist down. She smiled and said, "let's go." I gave in.
I let her drive us downtown. I hurriedly walked my wife from our motel room to the car, trying unsuccessfully to not let anyone see us. It felt weird sitting down in the passenger seat with only the thinnest layer of nylon between my butt and the cold, slippery leather. That was nothing compared to the surreal feeling of getting out of the car, locking it behind us, and walking away with both our butts on display all over downtown New Orleans--Canal Street, Bourbon Street, Jackson Square, down the river bank and St. Charles Street. As I saw people of both sexes wearing even less than I was, I eventually got used to wearing my costume. The rest of the day was great fun.
