I've been invited to the wedding of my Waxer. She insists I wear my Kilt, and told me to "show off her work." She's a pretty cool young woman!
I checked them out, but am disappointed that one cannot specify a number of measurements, as well as the length. I always like my kilts on the short side for more air-circulation. With these guys, their only size selection is basic S/M/L/XL. There is nothing that I found about length, waist or hip measurements - it's all generic sizes.
It sounds like she may already know if that’s the case maybe tell her just don’t bombard her with everything early on. I thought similarly and was afraid of losing my wife if I told her it sucks to keep that secret to someone you are that close with. It worked out for me coming out to my wife I hope it works for you
