I typically wear a 32B standard bra. By the size chart I'm solidly a size S in Kamo. For featherlite bras I've found that a M is best because I get some spillage on S.
I got this bra in a S and have worn it for upper body lifting and cardio workouts so far.
The sizing: Runs a little large. I can still wear it, but would probably size down to XS for future purchases. The width goes RIGHT up against my armpits and the bottom band doesn't offer as much support as I'd like, which I imagine would be helped by sizing down. A friend of mine with a different body type and larger bust got the same bra and also felt it ran large.
Design: I appreciate that the neckline hits below clavicle, so it doesn't feel like I'm being choked. The straps are thick and sit very wide, giving a more open back effect than I've seen in other bras. This also causes my back to look wider than usual. My whole upper body looks extra muscular somehow. Paired with the Alura leggings, only a couple inches of skin show.
The fabric: Love it. Brushed, super stretchy, opaque, and somewhat warm at rest, but dries quickly and wicks sweat effectively. Way less fur-attracting than featherlite. Colors are gorgeous.
Comfort: Very comfortable. Love the sewn-in cup pads and thick straps. Wide strap placement means it doesn't cut into the traps at all, and the more open back leaves the lats free to move as well.
Support: Low-to-medium, definitely lower than expected. Would likely be improved in a smaller size.
Tl;dr: Consider sizing down, especially if between sizes. Comfy, high coverage, less supportive than expected.
