Sizing is SMALL..I recommend ordering a SIZE UP FROM NORMAL SIZE. I ordered two in S first and they did fit, but I felt like they were choking me in the chest area. I ended up ordering the same two colors in Medium and they are very comfortable! I love the racerback style when doing yoga or working out as it doesn't "cut" anywhere.I like the LONGER LENGTH as it covers well beyond the hip and stays in place thru a complete yoga workout w inversions, etc. no tugging to prevent revealing the torso at all. The fabric is thicker than Lululemon's, but is soft and cozy feeling. I like the thicker fabric as it absorbs the sweat w/o revealing, etc.I am 5'4", 120 lbs. and 32C and the M is perfect for me. The support is comfortable, but NOT for high impact sports like running...good enough for low impact though.I chose the Harvest color, which I thought would look a bit more like goldenrod. In reality, I would say it is identical to Kraft macaroni and cheese, the color of which I fortunately like. Got a large and fits really well through the torso, but I really wish there was more room in the bust. I don't want to have to size up and sacrifice the good torso fit for more room up top, but alas. Also, I didn't realize there is a shelf bra - something I typically avoid as I always have to wear a sports bra for support regardless of what the tank offers. That being said, this tank is super soft and comfy. I would consider buying another in the future, but might size up for the ladies.Love anything from Beyond Yoga. I usually don't wear tops like this, with a built in shelf bra, because I have a very large chest, and I need way more support. I was surprised to see that this top actually supports my chest.If you do not feel comfortable wearing body hugging tops for exercise, this isn't a top for you. It is nice and long though!I actually purchased it as "motivation" as I slim down a bit more.Sizing, I usually wear a size L in most BY tops to fit my bust. I am a 36DD, and I wear a size 8 in clothing. I have gone up to an XL in some of their tops, and they are a bit too big, but fit my chest perfectly.I was so excited to find this top and have since ordered two more. I am 5ft 8, weigh 144 pounds and have a really long body which makes it almost impossible to get sports tops that are long enough not to ride up during exercise. I wear them for running, spin and circuit training . I do think the sizes are not accurate though. I ended up buying and extra large to fit size 36DD boobs. I don't carry any extra weight so I don't think these tops are suitable for overweight people. They are a little bit expensive but I think it is worth it to find a comfortable top for training. Looking forward to ordering one in each colour !This top is cute but definitely ran small for me. I am on the small size of a size 8 and the medium was much too small. I returned it for a size large and it fits much better. Very form fitting. I am going to wear it to a few classes and will post an update if i change my mind about the sizing and fit. I have never had and issue with Beyond Yoga quality so I expect it to wash nicely.Totally worth the cost of the $54.00 that was paid. Holds me in, doesn't ride up & is a saturated color. A tag on the top states the color may not be colorfast, wash in cold water before the first wear, separately. I'll follow that as I don't want to sweat navy blue! For sizing reference, I wear a medium in Kira Grace, and a ML in Electric Yoga. Really glad I ordered a large in this top. I'm 5'5'", 128 lbs and 35D. Also, this company sent this item so fast! It arrived long before anything else in my order! Wouldn't hesitate to do business with this company again.I got an XS because that's what I usually wear in yoga tops but this one taught me that I need a S in Beyond Yoga. It's still soft and beautiful, but it's tighter than I'd like and I always feel like my boobs are going to be pressed out in something like downward facing dog. I tried wearing a sports bra underneath but that made everything worse: I felt like I was in a corset and couldn't breathe. Now I get S Beyond Yoga tops.I would have given these Beyond Yoga Long Racerback camis a five star rating, but they were ridiculously undersized; based on my measurements, I ordered the small size; should have ordered a size up. I can wear them--and they are well made and I love the colors--but I have to struggle to get into them. I should have paid attention to the other reviewers.
