Love my new groundhog long sleeve t. Getting ready for fall. Just happened to relocate a cute, chubby groundhog to his new conservation land home - instead of under our garage. 😸
I love the color I chose, a blue colorway. Fits really well. I love the bees on the front. I am into caring for bees, especially Mason and Leaf Cutter bees. I raise them each year to fly around my flowers, clover in my front yard and my vegetable garden. I will definitely buy more tees from this company.
I love everything about this shirt, except I wish these shirts weren’t so long! I’d love them to be at hip length instead of butt length. As it is, I have to cut about 3 inches off the bottom of the size Large I ordered.
I love my new long sleeved shirt. It’s nice heavy cotton and so well made. The pine tree design on the front is beautiful.
This was my first time ordering from your company but I will be sure to frequent it again I’m very pleased with my purchase the quality is great and the fact that it was pre washed and not shrinking with washing is a huge benefit
Very happy with the print quality, the color and the size.
I gave this shirt to three of my family members for Christmas and they all loved it! The fit was great!!
Recently visited the shoebill stork at Dallas World Aquarium ... the gift shop had NO shoebill items! A search got me to BeCause tees... Surprised my husband with the shoebill tee and he loves it...asked to get one in every color...lol... Excellent quality and print... Quick delivery... updated at every step! thank you!
My new and very favorite shirt! It's beautiful, comfy, and I like announcing my loving support for butterflies.
This is my second long sleeve Tshirt from here and I LOVE it so much! I’m in animal care and take care of a lovely old bear who has my heart! I’ll always treasure this shirt too!
Now to decide on my next long sleeve Tshirt design!
Love the messaging and material!
Great color and material! Comfort Colors is my favorite brand to print on!
Saw this design and it was so simple but cute so finally decided to get one. I was complimented by a couple people at work and a random stranger on the train. The shirts as always are soft and comfy and you can’t go wrong with a hairy coo!
Looks great and fits perfectly. I will be ordering more.
I love my shirts and I have a lot of them. Great quality and heavy material. Not a Walmart tshirt!
As always, Michelle's artwork is wonderful, you provide a quality product, and thank you for a speedy delivery.
I'm 5'5" and 130 lbs. and I purchased a men's large (I like comfy, BIG shirts). I find that the large isn't really all that big and the cuffs are (surprisingly) tight on me - I can't imagine a man getting his hands through these cuffs. Even though I checked off "True to Size", I'm unsure if the fit is True to Size since I have never ordered one of your T-shirts before. I think I'll continue to order your soft Cali Wave Hoodie Sweatshirts which are my most favorite!
Anyone who knows me knows that I LOVE Giraffes and Elephants. When I first stumbled upon BeCause Tees I was overwhelmed at all the options for shirts! I ultimately decided on this long sleeve elephant shirt and the short sleeve crewneck giraffe with the bird shirt, as well as a sabertooth tiger kid's shirt for my son. I previously ordered the dolphin v-neck shirt for my sister. All shirts are amazing, comfortable, and stylish!! I can't wait to wear the long sleeve when it gets colder and I can't wait to order more! I loved the steel blue color for this long sleeve as well as the pacific color for the crewneck!!

Do your shirts fit true-to-size?
This is a difficult question to answer because everyone has a different body type and a different preference to what is their "ideal fit".
