Runbeam Short Sleeve 3.5 5 35 35
A weeee bit tight in the arms I am 5'2" and 125 pounds. I flunctuate from a 4 to a 6 in Lulu tops; if there's sleeves, I normally go with the 6. I don't have massive biceps, however my upper body is a bit more built than the average girl my size. The Runbeam is super flattering and so light that you don't realize you're wearing it. If you do have an athletic upper body, just be aware that the sleeves are cut a bit high and a bit tight. Again, I love this top, so this wasn't enough to make me return it, but it would be even better if the seam was let out at the bottom of the sleeve. March 6, 2015
Disappointed I have this shirt from a year ago in black and it is my favorite go to shirt. I was so excited to see it on here and so I bought the exact same size. It totally fit differently and not in a good way. The seams on it were in a weird place and the material was not nearly as soft as the one I have, I am guessing that is due to the patterned material. Please go back and make this in solids cause it was originally amazing! January 14, 2015
Great!!! I was in my local store yesterday to get an item hemmed. I saw this top as I was leaving marked at $34.00. It was in a size 2 and I tried it on and LOVE IT. Fits perfectly, material is so soft/sleek and really cute. Great score for me :) January 7, 2015

Nice shirt, but poor care in shipping out! I bought this shirt along with a few other shirts and although the shirt fits well I was disappointed to receive this shirt with the sensor still on it right smack on the front of the shirt. I am disappointed to think that Lululemon would not assure for quality control and ensure that their sensors are removed from their clothing before shipping out. To me, it seems like poor customer service. For sure, they would check the shirt to make sure there is no sensor on it before shipping, no? I understand human error but this is just a bit ridiculous.

Nice and lightweight t-shirt I picked this up on sale for 24 at my local store. It's TTS, a bit on the short side which I like as my waistband from my bottoms slightly peek through so it shows off my great LLL waistbands splashed with color(s). The reason for 4 stars is the fit in the armpit area, the cut is quite short so it takes a bit of getting used to and feels a little off. This is a pretty basic T, but as mentioned, the material is great along with the shorter length (considering most LL tops are pretty long) and the little pocket is a cute feature but really isn't all that functional.

Great Shirt! Love this shirt! I got the black and wore it the first time on a 10 mile run and it was perfect! It really helped me stay cool and dry feeling better than any of my previous run shirts. No rubbing or anything either, the shirt was totally comfortable and moved well with me! I highly recommend this shirt! November 16, 2013
Be cautious of the zippy green color! There's something with the zippy green color that causes it to react and stain after coming in contact with things like lotions, underarm deodorant, perfumes, anything! The first time it happened, I immediately washed and most (not all) the funky orange-pink stains came out, but after it happened a second time, I was done. I have 2 items in the zippy green color, a free to be bra and this shirt, and it happened with both items. I won't be buying anything else bright colored from Lululemon again. Lesson learned.

Love this! I purchased this shirt because I was looking for a bright, short sleeved shirt to wear for an upcoming marathon and this one fit the mark. I wore it in the race and it was super comfortable, light and no chafing. I usually wear a 6 in lulu tops and this one felt true to size. The only thing that I didn't like about it is that it is fairly plain. I usually purchase singular color tops and I love feminine details (subtle ruffles, etc). However, this is really a plain tee. It is super functional but I'd be more likely to give it 5 stars if it had some subtle details. October 29, 2013
Discoloured! Terrible product. I have this shirt in black and I like it so I bought the lime green colour. The first time I wore it the shirt discoloured under the armpits, turning orange as soon as I started to sweat. It is completely ruined and I can't wear it as it is super obvious and ugly. I have never had stains from any deodorant product on any other clothes of mine, it is clearly this shirt, the discolouring is not a stain on the inside but is actually a change in the fabric colour.
