The Core V Long Sleeve by Forme®, with all the smart self-correcting posture health benefits you love, now with extra coverage and support. Perfect for everyday wear, lounging, travel, or sleep, it combines comfort, style, and effective alignment correction.
Made from the same ultra-soft, breathable, and eco-friendly Tencel™ fabric as our signature Core V-Neck, this long sleeve features dual layers of patented intelligent construct design with muscle memory technology for a stronger, more supportive fit. It gently engages your muscles to keep your shoulders back and your spine aligned, helping to ease neck, back, and shoulder pain, without restricting movement.
Why Choose the Core V-Neck Long Sleeve？
✔ Advanced smart scapular alignment technology, stronger than the standard Forme® bras
✔ Silky, organic fabrics for luxurious comfort
✔ Clean, logo-free chest for a minimalist aesthetic
✔ Extended arm length to promote shoulder health and ease of movement
✔ Alignment autopilot technology inspired by Forme®'s Core V top
Unlike compression wear or taping forcing posture into place, Forme brand’s approach works with the body’s neuromuscular system—supporting the muscles responsible for upright alignment and back health, so posture improves through use, not effort.
In an era obsessed with quick fixes, Forme invests in what lasts: physical resilience, sustained movement, and the quiet strength required to carry a full life.
Developed by an orthopedic surgeon for his mother, who battled late-stage cancer and suffered from poor posture and compressed lungs, Forme® was created to empower people with health, strength, and confidence.
Fit Tip: If you experience pressure under the arms, consider sizing up or layering the Power tee over a light tee to ease your transition.
How to Wear Forme®?
Forme® is designed to be worn as part of your everyday routine, at work, while traveling, during workouts, athletics, rehab, post surgery, or even while sleeping.
✔ Begin by wearing for a few hours per day during the first 1–2 weeks to allow the body to gradually adapt to changes in muscle activation and postural alignment.
✔ An immediate improvement in posture may be observed upon wear, without conscious effort, due to the smart apparel's integrated alignment technology.
✔ Mild muscle soreness may occur within 1–2 days of initial use, similar to muscle adaptation or training fatigue. If discomfort occurs, discontinue use for 1–2 days before resuming wear.
Full Body Alignment: Pair with the Boost Short, Sculpt+ Legging, or Sculpt Short 8” and the Arch Booster Sock for complete support.
Advanced Support: For spinal disorders or pain management, layer the tee over the Power Bra or Revive Bra. Visit our Health Benefits page for guidance on musculoskeletal conditions.
✔ HSA/FSA Eligible: To use HSA/FSA funds, please check out with Flex. Receipts cannot be issued post-purchase.
Forme®'s wire and sensor free wearables use a patented construct of lightweight, multidirectional tensile materials to engage muscle memory for biofeedback and instant proprioception. Our patented technology enables the body to relearn its best alignment spatial sense to keep your back straight, reduce pain and stiffness, and elevate your physical function.

Reviews
I am new to using
"I am new to using Forme bra and clothing. I have found in a short time that wearing Forme had improved my posture from the start. I look forward to continued use and improvement reducing neck and shoulder pain along with overall better alignment."
There is a lot more
"There is a lot more compression compared to the bras. I prefer to wear this during workouts to help with my posture and prevent injury or pain. It was a bit difficult to get on at first and took some adjusting and getting used to. I will size up next time I order to see if this makes it more comfortable and less awkward."
Perfect support for walking and
"Perfect support for walking and lifting."
Love this under whatever I’m
"Love this under whatever I’m wearing to keep my posture aligned!"
These feel great. I love
"These feel great. I love to layer with other shirts. It isn’t super heavy. It really helps hold everything in line. I have scoliosis and helps so much with my back pain."
Great products!
"Great products!"
Subtle but effective posture support
"I notice a real difference in my posture when I wear this tee. It’s gentle but encourages my shoulders back naturally. I use it for walks, errands, and even light stretching. Pairing it with the Sculpt Short and Arch Booster Sock gives me a full alignment boost. The long sleeves feel cozy without overheating."
Great layering piece for daily wear
"I love wearing this under sweaters or jackets. The long sleeves give just enough coverage and warmth, and the posture tech is noticeable but comfortable. I recently wore it with the Ergo Short for recovery work at home, and it really supports my upper body. Definitely a staple for my wardrobe."
Perfect for daily alignment
"I’ve struggled with shoulder slouch for years, and this tee really makes a difference. It feels soft like a regular long sleeve but subtly guides my posture all day. I layer it over a light tank sometimes or pair it with the Power Bra for added support. I can wear it casually or under a blazer—it looks polished enough for work."
It’s a small adjustment
"It’s rare to find a long sleeve that looks cute and supports posture. The fabric feels soft yet structured, and I noticed my shoulders naturally align better. I wear it casually or layered over a tank for recovery days. It’s a small adjustment that makes a big difference in my back comfort."
Q&A
- I typically wear a medium or large with bust measurement of 39 do I need move up to an xl?
- Hi Donna, thanks for your question! To recommend the best size, we’ll need both your band and cup size rather than just the bust measurement, as our sizing is based on standard bra sizing (for example, 34DD). If you can share your usual bra size, we’ll be happy to guide you to the best fit! For further assistance, feel free to reach out to us at hello@forme.science.
- I’m a size 4 but have a 34” chest. What a ze would you recommend for the Core T?
- Hi Nina! For more personalized sizing guidance, feel free to email us at hello@forme.science.
- My problem is my lower spine and sacrum. Will the shirt help that low on the spine?
- For better information, we would recommend emailing askexpert@forme.science.
- I AM CONFUSED WITH SIZING. I AM A SIZE 38B BRA AND SLACKS ARE SIZE 12. I WISH TO PURCHASE THE REVIVE BRA , SCULPT LEGGING AND THE CORE V-NECK LONG. WHAT SIZES DO YOU RECOMMEND FOR ME?
- If you would like to send us your bra measurements, bust line, band line, chest and waist, we would be happy to assist you in finding the correct size for you.
- Can you please explain what the difference is between core v neck and ace v neck
- Hi Janice! The notable difference between the two items is that the Core tee is made with modal, which is a natural fiber that feels more like cotton. The Ace tee is a lighter fabric and tends to feel more breathable during highly active situations. However, both are great at posture correction and improvement in a variety of situations.
