Love the cut of this bra. Something about the squared neckline is super flattering. This Body Basics line is quite supportive too with the double lining in the bras.
Size note: 30in underbust; 33.5in bust
Recommend using your band size not your actual "Underbust measurement" to size. For example, my actual measurement makes me a 32C in a band and cup bra from Skims, so I would use the 32 to size in these bras not my actual measurement of 30in.
I ordered a Sm instead of the recommended XXS since that seemed very atypical for me. It fits fine and looks good (thanks to good elasticity), but XS would likely have been perfect size for me. I'm saying it runs small based solely on the sizing chart.
