This tank is advertised as a slim fit but it's also a bit short as well- much smaller than the other small Reebok Les mills tanks by comparison. I'd recommend going a size bigger than your normal size for comfort and look.
Love these pants. They don't ride up on the leg and have very comfy fabric. They are somewhat heavy material though, which is great for winter runs. A bit concerned about how the waistband will wash though, as it started to roll a bit toward the end of my exercise. Overall, good value for the price!
I always wear a small in pants- both Reebok and Nike. I ordered them for the look and fit. However, once I tried them on, the length was super short- barely covering my knees. I am on the taller side- 5'7" but have never had this problem before. I'll stick with the 3/4 capris from now on.
