Call me old fashioned but I always match a diaper cover with any dress my daughter is wearing. And nothing is more fun than the monogrammed diapers covers I've found on Etsy. Several shops on Etsy offer these white cotton covers with prices starting around $9. You can get your favorite kid's name, initials, or even a stitched design. Easy to mail in a cute padded envelope, these make fun gifts too! I recommend searching Etsy for a shop that matches your tastes in fonts and thread colors. Just be warned -- there are so many cute choices out there, you may not be able to stop yourself from buying in multiples.
