So, I get that Leolines is all made by one person, and she's doing us all a really great service, but I was disappointed by the quality after buying four and having the threads give out for three in the span of a few months. I'm still a novice steamstress, but I feel like splitting the most vulnerable point of the garment into two pieces of fabric (right where the tuck is) might be a design flaw.

Overall, I personally prefer TomboyX. The stitching method is better and has stood the test of time for me. And PAKA Apparel undies actually tuck surprisingly well too, despite not being made for trans women.
