A Gift

Cute design. Was a bit too large.

Very happy with shirt!

I loved the shirt I have been wanting the watermelon floral shirt! However I didn’t want to pay the full price so I ordered a mystery shirt hoping to get tattoos one and I did! So excited that they say my algorithm and sent it to me! Also very fun opening the package and seeing your surprise!

Love the tee so much! So cute and fun! Not like anything I’ve seen on the site before! As always, I love what Shelly Cove stands for.❤️❤️

Went with the mystery ones because who doesn't love surprises!

Amazing Deal

I ordered shirts my myself and my oldest daughter. I loved them both. They were not duplicates of shirts I already had. In fact, my daughter's shirt was a brand new release. What a great deal!

Mystery T!

I ordered one for me and my daughters they couldn’t have picked better! Mine was yellow and had flowers which I loved and her shirt was her favorite teal/mint green color! We love them!

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!
