The knot scrunch on the front of the shirt is not tied, it is sewn in to ensure it will never come out!
SIZING: RUNS SLIGHTLY SMALL, if you are in between sizes we recommend sizing up.
Ordered a size up from my normal and was very pleased! Originally ordered a medium in the yellow (which is a beautiful flattering yellow in person!) and it was a wee snug for really working out. Sized up to a large in my next one and is totally perfect crop length and move-ability! I am 5'3'' & a 38B for reference :)
I was quit surprised on how well the shirt stayed in place during my work out.
I got the xs and it was perfectly snug yet I was still able to breath and have all of the flexibility I needed to get a great workout in.
