Love Love these tanks I am wearing a size small. I have both small and xs and ai like them both. I will say when you size up it makes the shoulder straps a little bit long. But I am a shortie!! absolutely obsessed with these tennis skirts. I own four colors now. Just like the tanks I have both size extra smalls and smalls. The extra small is a tad short and the small is a tad long so I feel like I’m right in between sizes but honestly, I love them both. I also got a small in the biker shorts
