The Loafers I bought are insanely comfortable. Wore them the whole day on Bree Street and my feet didn’t hurt once!

Hi, I’m ELEANOR. I’m a single mother to a wonderful daughter, Emily.
I’m the founder of Olivia Boutique California and have run it for nearly 29 years. This boutique meant everything to me and was our path to a better future.
But earlier this year, Emily was diagnosed with a serious health condition. She needs more care, more time, and more of me.
With a heavy heart, I’m holding one final Clearance Sale up to 80% off, to clear everything out before we close our doors for good.
From the bottom of my heart, thank you for supporting me!
