Just got this tonight, haven't even washed it yet, but I love how it fits. I'm 6'1" or so, kind of a lanky frame but not overly so, and a lot of onesies are so dang long so I look for ones that aren't. This one is just perfect in fit for me.
I ordered a large size because it said it was 31" long and by gosh, it fits great. And even if I have a few boosters in my padding, with all the snaps, this thing will not come undone. Thank you Tykeables, I may need a few more.
