    The pants are of excellent quality
    Size: XX-Large, Color: Mauve/Apples
    The pants are of excellent quality, made from thick material that feels very warm. By comparison, the long-sleeve T-shirt is thinner and not as warm as the pants.

    Who doesn't love a unicorn?
    Size: 2T, Color: Pink/Unicorn
    Cute set but runs a bit big in my opinion for a size 2T. My grandbaby is tall for her age (22 months), but the pants were really long and loose on her, granted she's not chunky, so factor that in. Overall, it's a nice set and the material is soft (especially the pants) and seems like it would keep the little ones warm.

    Cute outfit for everyday.
    Size: 2T, Color: Pink/Unicorn
    Exactly as pictured. Good quality, not too thin but also not too thick. True to size and looks like it will keep my baby warm when she’s inside. Good price on sale! Was a steal!
