Fit is perfectly fluid, JUST like how you see it on the model in the striped version. Very good structure on the neckline, shoulders, upper arms, cuffs and welt - which makes all the difference. I do not think it runs big if you want it to fit fluidly LIKE THE MODEL. You need long arms to wear the style because the blouson silhouette can overwhelm. Soft and not too thick, and with a neat and tidy neckline. Works on a range of bust sizes. The red is a shade of watermelon, and not tomato. The stripe is very bold. Not good on petites unless you have regular proportions up top. Read the rave reviews.
