I found those duplicates odd too, but that's how they appeared in the Database - they were two separate pictures (as in, each had its own link on Imgur) posted under two different outfit entries. IIRC one of them was listed for a child bottom default even though the picture is for adults, so my guess is that the previous mod recycled the pic to save up time? I can't know for sure though, those defaults are from before I was a mod here.

All this being said... do you know if your jeans default is listed on the Database? If it isn't and you still have a working link, please shoot it over to the Sticky so I can add it ASAP!
