I wanted to order a strap on for some time. I’m a plus size girl and was afraid that it wouldn’t fit. This one was completely big enough and then some. I’m a 22/24 size and there is ample room even if you were bigger. It is totally adjustable and functions perfectly and my husband was thrilled when I walked out wearing it and I’m sure your partner will be too!!. The dildo that comes with it is nice but we have also tried our old favorite and it slid right in through the ring and fastened down perfectly. So if you are concerned- don’t be! You wont be sorry!!
