My new favorite sports bra
Size: Small, Color: Black
Best sports bra I’ve purchased on Amazon. I wear sports bras every day either while working or to work out. This one is my new favorite. I got a size small and am a 34B or a 36A. The fit is better than my Lululemon. It doesn’t dig in and the adjustable shoulder straps make it fit more or less snug.

Fit design.
Size: Medium, Color: Slate Grey
The fabric is really comfortable and it's well tailored! But I need cup room and this fits across me like a bandage, feeling like it mashes me flat. I removed the pads to allow more room for comfort, but it still feels too confining. If you're a small bra cup size, it will be comfortable.

Perfect top
Size: Large, Color: Flamingo Pink
This sports bra is so comfortable and gives the right amount of support. The color is the same as photographed. This top pairs nicely with their leggings. Good quality for what you pay. True to size, will order in other colors!
