Love it!

I love my shirt! I was having trouble picking which design I liked best so decided to let them pick for me. I was a little nervous but I ended up with a super cute blue shirt! The shirt is so soft too I love it! I also love how you get the turtle tracker with an order!


I was worried about getting an orange or yellow shirt and I ended up getting a yellow shirt, "Happy Daises." However, I love it. It's not something I would normally buy but it's super cute and I can't wait to wear it. I love the mystery when opening my package.

Mystery shirt

I love my mystery shirt. It’s a fantastic shade of blue. It says Shelly Cove on front in white and on back is a sea turtle out for a swim. I love him so much. I was going to order this design but it was sold out. I usually wear V neck shirts because crew neck come up to high and choke me. This one was perfect tho. I’m going to wear it to the aquarium!

I love knowing that my purchase is making a difference. For reference I am 5'3" and I wear a small, if i want it oversized I order one/two sizes up!
