One of the things that Vivian has worn throughout her life, in bigger sizes as she grew, are her Taylor Joelle Pretty in Pink tights. I love these tights. They're a nice, thick fabric, so they hold up well to a baby crawling around or a toddler's busy schedule. The feet have non-slip grips on them to help if you're putting them on a walker. Vivian currently doesn't own any shoes that fit well, so she's just been wearing these tights a lot when we go out instead.
I picked my tights up over at MamaBargains (I'm pretty sure), but if you can't find them on sale somewhere, they're definitely worth paying full price. You'll get a ton of use out of them- and even better, you'll get so many compliments on your little girl's cute outfit!
Disclosure: I received no product and no compensation for this post. Just writing about something that I bought and that I love!
