So, I read all the reviews for this product in hopes to find out if these shirts run small or big and was surprised that no one had commented about that! So, I was the lucky one to buy one in every size pretty much. I even measured myself to find the proper size. The small is SMALL... I am a size 8-10 typically a medium in shirts and the large fits me great. I wouldn't say that this shirt is really a "unisex" considering the large fits me perfectly. These shirts are extremely soft and very easy to wash! I would definitely recommend this shirt... just be aware of the sizing. Nice stretch to the shirt, too. I would say if you are a female size 0 to 4 then the small would fit you. Size 6 to 8 would be a medium and size 10 to 12 large. Hope this helps whoever in their purchase of these awesome shirts!!!!
