Sizing Guide

At Riah Jane & Co, we focus on pieces that feel comfortable, easy to wear, and designed for everyday life.

Because we source from a variety of trusted partners, sizing may vary slightly from piece to piece—but we provide notes on each product to help guide you.

How Our Pieces Fit

Most of our styles are designed with a relaxed, wearable fit.

  • True to size for an easy, everyday feel
  • Size down for a more fitted look
  • Size up for extra room or layering

We’ll always include specific fit notes on each product page so you know exactly what to expect.


Between Sizes?

If you’re between sizes, we recommend choosing based on how you like your clothing to fit:

  • Prefer a closer fit → size down
  • Prefer comfort or layering → size up

Fit Notes You’ll See on Product Pages

To help you shop confidently, we include notes like:

  • “Runs slightly oversized”
  • “True to size with relaxed fit”
  • “More fitted through the chest”

These are there to guide you—not confuse you.
