I am obsessed with the fabric on this sports bra—it really does live up to the "buttery soft" name. I bought it for yoga and lounging, and it’s honestly comfortable enough to wear all day without feeling restricted. The square neck is super flattering and gives it a more stylish look than a typical sports bra. It fits true to size and the racerback doesn't dig into my shoulders at all. If you’re looking for a Lulu-level feel without the crazy price tag, this is a total win!

Runs large

Size: X-Large, Color: Ocean Blue

This bra runs large. Material is nice, style is good. The lower edge would be comfortable if I had the correct size. I’ll reorder a size or 2 smaller

Carefully measure your size

Size: Large, Color: Ocean Blue

So difficult to get over my shoulders I guess it's a little small for me. Comfortable but I don't want to take it off or put it on

Larger than life

Size: X-Large, Color: Ocean Blue

The fit is large! So go down a size. It’s soft and seems like good quality, but absolutely huge

Very good quality sports bra.

Size: Large, Color: Navy

Very good sports bra. It is high quality and made well. It is a full coverage bra which gives it good support but also makes it a little hot especially in warmer temperatures but at the same time it is very nice for cooler temps.
