Great customer service. I ordered a XL and mistakenly ordered a second XS. Customer service service ask if made a mistake in ordering the XS. We corrected the order and now I have 2 amazing XL tees to fit my farmer shoulders. Great job.

Usually when I see a comfort colors shirt I know the fit and comfort would be good however lately the shirts have been slightly short so they don’t stay tucked in which is not your fault however the constant emails asking for reviews is annoying. Without the nagging emails I would have rated it a 4 but because you keep asking for reviews you get a 2. Be careful what you ask for you might not like what you get.

Store owner replied: Hi James, I appreciate you taking the time to share your feedback. On the fit, Comfort Colors tees are vintage-washed and garment-dyed, which can occasionally lead to slight variations between batches. That said, they should still fall within the sizing tolerances I work to, so if anything ever feels off I’m always happy to take a closer look. On the emails, I hear you. Review requests are automated, but I’ll take that feedback on board. If there’s ever an issue with a tee, a quick email to me at support@happyplantpeople.store is always the fastest way to get it sorted. Best, Jo Happy Plant People 🌿

Should be N7, not N14. Smaller size than expected. Hopefully it doesn’t shrink. Like the color. Durable material
Lauren 3/5 Verified
Store owner replied: Hi Lauren, I really appreciate you taking the time to leave such a detailed review. You’re right that nitrogen’s atomic number is 7, in the design we used 14 to represent the N-14 isotope, which is the most common form found in nature, but I can absolutely see how that feels a little inconsistent next to phosphorus (15) and potassium (19). That’s such a helpful note for me to keep in mind when I’m working on future versions. On the sizing, if the fit you received feels off compared with the size chart on the product page, just lay the tee flat and send me a quick photo of the width (armpit to armpit) and length (shoulder to hem). If it’s outside the tolerances, you’re completely covered for a free replacement. I’m so glad to hear you’re happy with the color and fabric, customers are loving Comfort Colors™ fit and quality right now, and your feedback really helps me keep improving as I grow my small business. Best, Jo Happy Plant People 🌿

I ordered to small to start with and ended up having to order a larger size. Will rethink before I order large again.
