Super comfortable sports bra/bralette! Not the most supportive sports bra I've owned, but a great overall bralette. The support this offers is more like a light impact bra, but for the price, this feels really well made and is really easy/comfy to wear. The stretchy material keeps everything in place comfortably with just enough compression.
If you are busty, this will not offer the support you need for the gym. If you are above a B cup, this would be described better as a light impact sports bra. The bottom band is not very firm, so I would say this is better suited to light support activities or loungy days around the house. I wear a 30G (30DDD us), so I need a small band in the ribs but a generous bust and this bra in a Medium fits me very well, without any spillage from the sides and feels secure on my ribs. This is not supportive enough under my bust for me to want to wear it to my usual barre classes, but is great for casual errands and generally being comfy. A Small might have fit tighter/more supportive in the ribcage, but I suspect would not have been generous enough in the bust to cover me up.
There are removable pads, which I didn't need, but might be a useful feature for someone looking for more shaping. I ordered this in zephyr heather, and it's a very pretty pale blush. Material doesn't seem like it would be see through if you like wearing just a bra as a top to the gym.
