Little Sleepies bundle best

Product Name: Little Sleepies bundle best
White 3-6 ruffle zippy Wisteria best 3-6 zippy Sweet treats 0-3 zippy All play condition, not first owner for any of them. Besides wash wear, issues are listed below, no holes that I've found: White is play just because it's a bit dingy looking because it's white. And has a a loose thread at the seam around the neck as shown in pictures. Wisteria is dingy at the top of the zipper and a bit at the cuffs. Sweet treats has a stained/dingy top zipper as well and is a little harder. Not sure how to treat, didn't want to make worse. Bought all of these in a bundle when I first got into LS and wore as is.
