I love your shirt. Wish it could have made my daughter change the plans she had in her head. She took her life last Saturday. I’m torn apart, my baby Alli is gone. I do love your shirt and I work at a physiatrist hospital so I am like a walking billboard.

I love this shirt. I got it as a small although it was a mistake, but I used it as a gift for someone that could fit in it. It matched the description, and it met her expectations. Thanks again for the shirt; I can’t wait to shop again soon.

I love the yellow shirt along with the ladybugs. It’s super cute together. I wish that they would be in a pink color, so that the design can pop out really well. It matched the description and met my expectations. Thanks again for the shirt; I can’t wait to shop again soon.

Super cute. Love butterflies a lot. I wish they have the shirt in teal, so it can support Suicide Prevention. Matched the description and met my expectations. Thanks again for the shirt; I can’t wait to shop again soon.

I loved what I got!! It is such good quality and even better of a meaning!! I recently lost my brother to suicide, and every time someone asks me about my shirt I am able to talk about him a little bit, and that means more to me than I can explain!! Absolutely AMAZING!!

I always love Happiness Projects merch, and I love the message it sends. I got another shirt to give to my partner since I believe he also needs to wear a reminder that he’s not alone. I appreciate and love my shirt along with other past purchases, thank you happiness project team 💚

It’s super cute. I love the berries and the details of it. I like how it’s vital to wear something to nourish myself. It matched the description and met my expectations. Thanks again for the berry shirt; I can’t wait to shop again soon

I love the shirt. It’s incredible for me to wear since I have autism; I got one for my neighbor since she likes butterflies as well. The one I have has a small, yellow mark on the bottom; however, I like having some yellow in it. It matched the description and met my expectations; it also met my neighbor’s expectations as well. I highly recommend it for any butterfly fan. Thanks again for the butterfly shirts; I can’t wait to shop again soon.

Wore it next day after receiving it. Love it. Love the yellow.

Very happy with the merchandise I purchased! However, since I placed my order I’ve received 1-3 texts + emails a day for various promotions, thank yous, etc. it’s been way too much marketing sent my way, and have since unsubscribed from it all and makes me not want to order anything again. I love the merchandise and the message behind it all, but way too aggressive on the follow up texts + emails in my opinion
