My wife next to never goes knickerless, especially if she is wearing a skirt. Occasionally she has come home from the gym wearing sweatpants and no panties because she has forgotten to take clean ones with her. That's about it... :(

She rather rarely goes braless either. Her bra size is 70E (~32DD) and she says she has too big boobs to feel comfortable going braless often. (I disagree!) But she has a couple of dresses that just cannot be worn with a bra. So rather interestingly she goes braless most often in parties and other occasions when more people can potentially notice it! And it really is rather easy to notice if one cares to look a bit more closely. This seems to turn her on too, I've a good few times pinched her erect nipples during the parties, and often she's quite ready to have sex when we get home. ;)

I'd bet she has accidentally given a few glimpses of her nipples too. Two of of the dresses are rather low cut, and one actually is slightly see-through too, but the pattern of the fabric easily hides this.

Going out with nothing underneath
 

Mine has wore a sun dress a few times with nothing underneath it, I had her do it a few times in case I wanted to fuck her some where while out. As well had her do the same with shorts if we would be out camping, she would have no panties under them or no bra under her t-shirt.

During our 5th anniversary to Miami Beach, my wife went pantyless during one of our dinners. Was so hot. We ended up fucking in the window of the resort later that night...didn't really care who saw us from other rooms.

Wifey does it often
 

My wife will often go out w/o wearing underwear, but only when we are going to a bar or club.

The attached pix are from last halloween weekend. The referee outfit was very small and thin, and she didn't wear anything underneath it. Everytime we walked up the main flight of stairs in the club there was a group of guys watching from the bottom.

From Western PA eh?

As mentioned previously, your wife is truly stunning ! Many thanks for posting these latest pics of her :) Her arse is awesome.

I don't! Poor planning! :(

yes sir

I met my wife we I was 19 and she was 18, she is now 48.
On our very first date she wore no bra, and, later she told me, no knickers, although I found by myself a few weeks later that she did not always wear knickers. I asked her if on that first date I had discovered she was not wearing knickers what she thought might have happened. Nothing at all would have happened she said, it was a first date. But it would have been a big turnon for me knowing that you knew and that you would try to find out at future dates.
We have now been married for 27 years and her attitude to wearing underwear has not changed at all. She seldom wears a bra, often goes out bare down there and it does not matter if she is wearing a long skirt/dress or a mini, she still leaves her knickers at home. I loved the attention that she gets so much that I encourage her and during our marriage she has often not only gone bra less but also waring a see-thru top. This has led to many exciting incidents that I may expand on if people are interested.
