Don't just take my word for it

Excellent 4.8

I was so nervous ordering online, but By Willa completely won me over. My Addison Linen Suit arrived in 4 days, the fabric is absolutely gorgeous, and it fits like it was made for me.

The photos don't do it justice! Super flattering, and the quality for the price is unreal. I ordered a medium and it fits perfectly, not too tight, not too baggy. Already added two more colors to my cart!

Jennifer R.

I needed a polished outfit for an important job interview and found the Addison Linen Suit in light blue. I got the job AND multiple compliments. The fabric is breathable, it doesn't wrinkle easily, and the cut is very flattering.

Rachel S.

I bought the Alessandra Maxi Dress for my daughter's outdoor wedding and I received so many compliments. At 57, I sometimes struggle to find things that feel both elegant and age-appropriate, this dress was perfect.

Michelle T.

Okay, I ordered the Adriana Sweatshirt on a whim and now I wear it literally every weekend. It's incredibly soft, washes beautifully, and the fit is relaxed without looking sloppy.

Verified

Ashley D.

As a plus-size woman, finding cute clothes that actually fit is a constant struggle. The Alexandra Cardigan fits me perfectly at a 3XL, the sleeves are long enough, the shoulders sit right, everything! I'm so grateful for a brand that actually thinks about us.

Patricia L.

Honestly, the price is SO reasonable for how put-together it looks. Shipping was fast and the packaging was really cute too. Will 100% order again.

I bought the Sweater as a little treat-yourself moment and it is absolutely worth every penny. It's the softest thing I own, I keep reaching for it over everything else in my wardrobe. Runs true to size, washes well, zero pilling after multiple washes. By Willa, thank you!
