I really like whatever stitch they do for aristocrats, b/c they stay up nicely and go on easily. I've bought some recycled wool longies recently and am having some issues. One is drawstring and that sort of annoys me for various reasons. One is elastic and I like it, but thought I read somewhere that that can cause wicking? One is neither, and is really tough to get on, though they stay up once I wrestle him in there. :/ I think they're just too small in the thighs and bottom.
So, what do you prefer? What do you think is best? I haven't used any of them for any length of time, except the drawstring one, which does work well, but doesn't stay up so well. So I'm not sure if that's true about the elastic and wicking.
