WHAT CUSTOMERS ARE SAYING

So impressed with the quality! It’s so comfy, and I love the pockets on it! The collar gives it a more preppy look, which I love! Matches the blue herringbone perfectly! Well done Day 1!

I love the fit of this bra! The built-in pads are my favorite! It’s a dream of a sports bra! It’s snug in all the right places, stays in place, is so comfortable, and the criss-cross back is so cute!

Megan

I’m 5’2”, 129 lbs; a medium is my go-to, and the medium is perfect. The most luxurious leggings I now own! These are beautiful, fit well, and feel good. Not used to the no underwear, though, but that’s just me. Love the underwear liner concept.

Colleen

Love this jacket. I have it in black, and it was my go-to jacket all summer… had to purchase it in the red velvet… which is a beautiful color! Perfect for fall! I sized up for a roomier fit!
