Fit with Confidence – And Consciousness
At Pima Prima® we want you to feel great in your T-shirt. That’s why we offer returns if you're not fully satisfied with your size. But we’re also here to address a bigger issue: the environmental impact of returns and long-distance logistics.

Every return shipped across borders contributes to unnecessary carbon emissions and packaging waste. Our goal is to reduce this burden by helping you choose the right size the first time — through clear measurements, detailed guidance and personalized support.

The problem we’re solving:
Traditional fashion returns create up to 15 million metric tons of CO₂ emissions annually and generate tons of landfill waste. We're working to minimize that footprint — not by eliminating returns, but by making them smarter, fewer, and more sustainable.

Wait! Don’t Go Yet! 👋

Don’t leave these cozy Pima Cotton outfits behind! 😊

Excellent quality!

This t-shirt is a standout! The thick, high-quality cotton feels both durable and soft, making it incredibly comfortable to wear. The fit is perfect, not too tight or loose, and works well for any occasion. The hidden gem is the cute print on the inner side that adds a playful, creative touch. It’s such a unique detail that shows thought and care in the design.

FINALLY!

I love and own many short sleeved tees. Favorite brands include Madewell, Everlane and Marine. They’re all 100% cotton, a necessity here in hot humid Florida. However I wish a lot of them were longer. Sizing up to for extra length meant a hugely oversized fit. Until now…I LOVE the length of this Pima Prima tee. I’m 5’5,” 165lbs and my chest measures 43” around (38C or 40B in Soma). I couldn’t find a size guide, (even on the retailer’s site) so per Amazon’s suggestion, I ordered XL. I’m super happy with the fit; comfortably loose. I don’t like a slim or body-con fit. At age 60, I’m a little self conscious of my upper arms, but the cuffs fit well, not snug. I’m also able to easily cuff these and they stay put. I don’t normally tuck my tees in, but there’s something really cool about the fiber content of this top. When tucked in, somehow it hugs my hips nicely, creating a smooth effect. I received this through Amazon Vine at a discounted price in exchange for my review. While the price may seem high, I think it’s fair. The material and quality of construction are excellent. Do I wish it were lower? Well yes, especially since I’d like to buy another one (or two) on my own. I’d really love to have one with a V-neckline. Not a dealbreaker for me, but felt it worth mentioning this tee is not a bright white tee - it’s more of an ecru or off white. I measured this laying flat and underarm to underarm is 21” (42” total). This curves in in on the sides, another great feature, and the waist is approx 19” (38” total). Bottom hem is 22” (44” total) and length is approx 27.” This also has some stretch to it, but retains its shape well.

Soft, good quality, pre-shrunk but has a few flaws

For reference, I’m a 36DDD/E or 38DD, with 38-28-40 measurements. I typically wear a medium or large in tops and a size 10/12 in dresses, depending on the cut and brand. The shirt I purchased is advertised as off-white (I added a pic to show how "off-white" it is in person when compared to 100 brightness laser printer paper), 100% Pima cotton, and made in Peru. I ordered a women's large, and it fits as expected. I’ve owned and washed this shirt a few times, so here’s my take: - The shirt is supposedly made in Peru from 100% Pima cotton. It's a heavier weight t-shirt as well. - The fit is relaxed, which I prefer, as I’m not into form-fitting styles anymore. - It’s pre-shrunk, so you can confidently order your usual size. Major downsides: - It attracts lint quite a lot, which is why I couldn’t rate it a full 5 stars - my other Pima cotton shirts (from other brands) don’t have this issue. - Is it worth $50? Honestly, no. The quality is good, but it doesn’t fully justify the price tag. Spending $50 on a Pima cotton t-shirt is steep, especially in this economy. Sure, you could argue that the cost covers fair wages for the Peruvian cotton farmers (though this is an assumption) and manufacturer overhead, which could make it a “fair” price. But from the average consumer’s perspective, $50 is still a lot for a single t-shirt. Overall, it’s comfortable, but the price and lint issue may be worth considering before buying.

100% recommended

It is very important to have basic shirts in neutral colors in the closet to be able to combine, that is why I am always in search of the perfect shirt; I have bought several in stores and online and they always end up looking of poor quality. They tell you they are cotton and when they arrive you see that they are not; But I do not give up in search of the perfect shirt, I kept looking and found this one; I ordered it to try it on and I must say that I love it, it is very soft and is 100% cotton as the description says and this is evident in the excellent quality of the shirt, it is a little more creamy white, but it tells you this in the description; I can definitely stop my search because I found the ideal basic shirt and I would order it in more colors. I am normally a M, but I ordered it in L and it fits me perfectly, I think for an oversized look I would order an XL; I am 5.5 and weigh 155 pounds.

Worth the money!

This is by far the nicest, best fitting, highest quality t-shirt I have ever owned. Did I ever think I would own a $48 t-shirt, nope but now I know the difference from the $10 t-shirts I have been wearing and it's substantial. I kind of regret getting it in a way because now I can't go back to the t-shirts I was wearing. And if you think about it, sure it's a lot of money for a t-shirt but I will wear this a lot more than any fancy expensive dresses or special outfits I have spent hundreds of dollars on. This will be worn at least once a week. I ordered a size M, I am 5'7" 112 lbs. and the medium is a perfect fit. I usually wear small. This shirt is so soft and comfy and well fitting. They somehow managed to make it not tight and not loose. Also did great in the washer and dryer.

Nice!

Has my body come to ease? I can't feel it yet, but this is a nice t-shirt! It's very soft. Is it pima? It says so, but I can't tell. It looks and feels like a high end t-shirt. The hems are wide and well stitched. It has a heavier weight and drape than most t-shirt materials, but is smooth and cool to the touch, not rough like some heavier weight t-shirts.

Great quality tee

This is a very well made t-shirt. It is a classic style; the color is vanilla, just barely off white. The fabric is very smooth and soft, nicely finished seams and is tagless. I am very pleased with this purchase, which is true to size.
