Sarah, I'm glad you found something that makes you happy and hope it continues to do so. I don't understand at all why you feel wearing those leggings/tights have anything to do with crossdressing. They're just a normal male piece of clothing that has been around for several years. That being said, if you want to buy more male leggings similar to those they are not rare at all and can be found easily. These are made by Under Armour: https://www.underarmour.com/en-us/me...pid1281108-001
and Nike: https://www.nike.com/t/pro-mens-training-tights-od3w1j
Both of these brands are extremely well known and can be found anywhere. There's no need to search out for some rare exotic item, you can just pop into your local sporting goods store. Hope that helps satiate your desire more easily.
I understand and can sympathize with those that feel they need to find some loophole to legitimize their purchase to their SOs. It's extremely ridiculous though (on their part, not yours) that you would need to show a link on the internet to do this. I highly, highly doubt anyone (male or female) would consider a pair of plain black leggings to belong solely to a women's wardrobe.
On the flip side of the label argument there is Wolford. I doubt anyone thinks they have ever designed anything for males and I'm sure many would consider there products to be very feminine. Yet, they have a webpage that purports to be just that: https://www.wolfordshop.com/men_hosiery.html
I find it really weird because it just lists existing products and swears that they are designed with males in mind! I would say that those products listed most definitely were originally created for just women. For any crossdresser needing the ridiculous excuse that it was labeled for males so it's therefore okay...Wolford has done the work for you. These most definitely are more feminine than those male sports leggings and you can "justify" your purchase. So just buy these because it seems you are just wanting an excuse because it has to be labeled "male" to be safe. I actually love Wolford's products, some of the best quality around and beautiful designs. And of course, actually feminine.
Anyway, the reason I am still responding in this thread is not to pick on Sarah but to inform others that you can buy male leggings almost anywhere these days. They are not at all an exotic item and are not only made by niche companies. If that is what can satisfy your CD needs just go to your local sporting goods shop and pick up a pair. It will be no different that buying a basketball.
