Anyone know how Rails clothing runs?

I really like this shirt/vest (found in the other post about "dress me for work"):

Anyone who owns things from Rails know how it typically runs? I've been reading reviews and just getting confused.
I'm either a Small or Medium.

Thank you!

I have a few Rails blouses, which I really like a lot. The sizing is spot on. I'm a "small" in just about every designer/retailer. Rails size S fits me as expected. If it helps I'm 5'9, 125lb, 32DD.

Just go with the size chart. I’m usually an XL and the XL measurements look a tad on the small to me compared to other brands. But they have provided a size chart so just use it.

I find it runs true to size.

I love Rails. I’m 5’8 135 pounds and usually wear a medium in Rails, with some exceptions. My more recent purchase were size small so perhaps their sizing is changing a bit.
