I did. I think I just called them. H bought me pj's from there as a gift last year, and a seam opened up on the shirt along the side of the torso similarly early on. I didn't have an order number, but they located the order by address/etc. and sent me a replacement top and a prepaid shipping label to return the one with a hole. Pretty easy.
I bought some PJs for DD1 last year and both pairs have developed tiny holes. I’m really surprised, the place they showed up are random and don’t seem like wear. For the price, I just expected better. I’ve heard their quality is going downhill.
I noticed that there is a seam unraveling from the PJs we got for BB this Christmas, I was going to let it slide because I don't have the energy for it TBH. This thread is making me reconsider and call/contact them to at least let them know. Maybe it will lead to a review of their manufacturing etc.
