I do think when you're going to slate a particular brand that it's worth knowing whether the thing you're slating is actually a feature of their products. I accept that they're divisive, but to my knowledge, Lucy & Yak have never produced jersey dungarees. 🤷♀️
Anyway, I like them, OP, but I own many pairs of dungarees, and pretty much live in them, so I'm by no means providing an unbiased opinion. For the price, though, I think you can get similar to those you have posted from Thunderegg for less.
