How do the adult pajamas usually run. I wear an 18 or an xxxl typically but an 18 on the size chart is an XL. Just wondering how I should size.

I’m so disappointed in the quality of little sleepies lately. I’ve been buying since my daughter was 5 months old and it was the start of my bamboo addiction. I’m not loyal to any one specific brand, I think all have great products. I’m also not an over consumer. My daughter has enough to wear and that’s it, between 7-10 pajamas and I only save one size ups. So needless to say I’m picky about the prints I buy. Well my Bluey obsessed toddler had to have the Bluey print. I knew that it was going to show wear as it’s a darker print but I convinced myself she needed it. Sure enough it looks horribly worn even with washing exactly as instructed. I’m very specific with how all my bamboo is washed. Well not only is it worn looking and dingy but the hemming on the shirt is coming undone! I’ve never had this happen to any of the many bamboo brands I own. I sent them an email a month ago and nothing. I’m just super disappointed. There is so much hype on the Facebook page but at the end of the day it’s just pajamas… and mediocre ones at that.
