I love the fit of this seamless workout T! It's very flattering and also very fitted. If you aren't looking for a T that is fitted, this isn't for you. Others have said it's a dup for Lulu, which I can't confirm. The T does stretch a bit when it gets sweaty. Love this so much and wish it was made in lots of other colors. I got the XS which gives me a nice fitted look ( 110 lbs/5'3.5").I bought this hoping it was a dupe for the Lululemon SwiftlyTek shirt and it comes REALLY close. I've done spin and running/lifting in this shirt and hit holds up well, wicks sweat and keeps its shape after washing/drying. My only complaint is that the material is ever so slightly heavier than the lulu version and the sizing is a bit different - I wear a 12 in the lulu shirt and it's loose through the midsection, and the XL in this shirt fit me well through the boobs but was more snug than I'd prefer through the waist. Overall, i'll be buying more of them and for the price point they are totally worth it!Very breathable. Keeps you cool. Not very stretchy. But looks good when running errands in gym clothes. Definitely run smallI bought three colors of this shirt for outdoor running in the spring and summer. I've also worn them casually outside my workouts. They're perfect. I'm 5'6, 32DD and around145 lbs and the medium fits well with some room to spare. I don't like my running shirts to be too fitted. If I want a more slim and fitted look, I'm sure a small would work just fine. These give the just right shape but do run a bit long, like several other reviews have already mentioned, and as you can see in my photo. I was kind of turned off by that at first. However, turns out the length actually works quite well during my runs because sometimes my shirts would run up my body which can be annoying. I've put them through the washer and dryer several times already and they've held up well so far. The material is super comfortable. I sweat a lot when I run in the summer and this shirt would be soaked in sweat but doesn't feel gross or heavy on the body. Wish they come with more colors for the soft version. Highly recommend.This is a great lululemon dupe shirt. Love the fit!I have the black and faded rose color. These tops are different types of material. The rose is a ribbed fabric that is not fitted while the black is a very stretchy thin fitted material. Look at the colors to determine which style you prefer. For yoga I wanted the fitted thin material, really perfect. Not so crazy about the ribbed material but I kept and use for other excercise.Update: these do not wear super well in terms of holding their shape. They’re kind of like wearing all cotton jeans, you wear them once and they make knees and the rear end is baggy. By the end of the day these tops are stretched out and ill fitting.Original: I am 5‘7“, 125 pounds, slender but athletic build, I bought the small, they are definitely fitted. They are long, material is not thin, seems to stay put, I got the vibrant green color, it is very pretty more of a muted jade green as opposed to an emerald or vibrant green. I also got light gray, equally as nice. Extra small would have been too small. The material is such that I think the medium would bunch up in the wrong spots and look messy.As other review indicated you need to size up. I'm usually a small and ordered M in green. When it comes to the fabric stretching , it does not. It's a little stiff when first arrived and after washing it did not "soften" up. As for the length it's good but it would not have that affect because it gets caught above the bottom thus not making the use of a full length shirt as desired.These tops are great when you get the right size. Sent the wrong size this time by mistake. Have several of these tops from CRZ Amazon. Good fit ,wash well and have some length. Good for inversions if you do headstands as it doesn’t drop onto your face.Would be 5* but Amazon selection went wrong in this occasion. Not a problem though as returns are easy. Thanks .You can tell the product is good quality. Runs small though. I am 10 UK size and I bough it in M. But runs a little small. M is ok for me but too stretchy I would say..its a matter of choice anyway. If you want it slighly loose and you are M, buy an L.This is identical to the expensive brand I won’t mention. The fabric and fit are outstanding quality. Would love some bright colours please.Lovely colour, fitted style, if between sizes then go with bigger size I think. Look is same as LLL Swiftly but fabric is not comparable, this is stiffer and heavier but a good alternativeDidn't like the material / fabric. Very loose ....too big.
