Perhaps you can't see them in all their glory, but these pants are 6-12 mo pants (Lukka is now bordering on his 15th month!) and they still fit around the waist...so... highwaters it is! They are a good 2 inches above the ground.
Trying on next season's clothes to see if they fit, here's a funny mugshot from the Bug. He looks haggard, no? Those jammies say 2T, luckily I noticed them at the bottom of the pile--they and the other T the Train set he got from his Aunty Krissy will probably only fit for 6 more months!
