This shirt is so soft and the unicorn-mermaid combo makes me smile every time I wear it. The cobalt blue pops beautifully, and it’s perfect for my whimsical ocean-loving side.

The cobalt blue color is even more vibrant in person, and the fabric feels soft and breathable right out of the package. Every time I wear it, someone stops me to ask where I found this whimsical unicorn mermaid design.

I’ve worn this tee three times already and the cobalt blue is so vibrant it makes me grin every time I catch it in a mirror. The unicorn mermaid mashup is exactly the kind of silly, whimsical energy I needed in my wardrobe.
