Between sizes: size down for a match fit, up if you train in layers.
The jersey is an athletic fit, not compression. It should skim, not grip.
Sleeve length on the women's cut is shorter than a unisex shirt of the same chest measurement. That is intentional.
Measure a shirt you already like flat on a table and compare — it is more reliable than measuring yourself.
