Excellent purchase ( especially on sale ) . I find this top true to size ( at least for me , because I am planning to wear only sports bra under ). If you want something more then go up 1 size . I am size S and this is what I order , and fit me perfect . I am 5.5 ft. tall ,108 lb.,32 C -D , 26 waist ,35 hip .But you have to be aware that this top extremely thin and same time extremely soft. I am purchasing Blue and White colors also . Highly recommended . Thank you . Hope my review will help you make decision .

Well, they're complaining.It's running too small.Well it is a little tighter than usual but I can wear my normal 2X. Love the style and color

I do not understand why there are so many reviews saying this runs small. I ordered up a size because of it but now I have a way roomy top. I could've easily wore my true size. In my opinion, there's no need to size up.

As others have mentioned, this top runs VERY small in size. Wish I had ordered an XXL rather than XL but they are sold out in color I wanted. With this poly fabric at least it will not likely shrink, and I will not wear a layer underneath. It is a nice thin fleece top, and I like the fit otherwise.

Runs very small. I'm usually a L and needed XXL. It's also thin but very soft and comfortable. I like it but it would have been good to know these things before ordering.

How could Columbia have gotten this so wrong. I bought an XXL so I could wear it over a heavy base layer, and it was skon tight. NOT a good look! Blue color was .. meh! Definately returning.

I know these usually run small so I bought a large and it fit like a small. If you are a B cup or under it may work. Returned.

Very pretty pink shirt. However, it's cut 2 sizes too small. I compared it to other shirts and there is such a big difference. I will be returning it.

Bought XXL and could not even get over my chest and usually get an XL. They are soft and lightweight. If I could have fit in them I probably would have liked them very much.

The size is not what is reflected on the shirt. It is about two sizes too small. I ordered an XXL and it fits like a L.
