Our Fit Philosophy & Size Guide

At Lumistelle, we believe a perfect fit is everything. Standard size charts can be misleading because every fabric and style fits differently. That's why we hand-measure every item to provide you with the most accurate sizing possible.

How to Measure

1 Get Your Measurements

Using a soft measuring tape, measure your bust, waist, and hips. Stand straight and relaxed while measuring for the most accurate results.

Tips for Accuracy

Use a fabric tape measure, not a metal one. Measure twice to ensure accuracy. Keep the tape snug but not tight.

What to Wear

Wear fitted underwear or form-fitting clothing. Avoid bulky items. Remove shoes or wear thin socks.

Common Mistakes

Don't pull the tape too tight or too loose. Don't slouch or hold your breath. Measure at the right position.

3 Understanding Our Fit Types

  • Slim Fit

    Designed to be close to the body for a tailored look. We recommend matching your measurements closely for the intended silhouette.

  • Relaxed Fit

    A comfortable, easy fit with room to move. If you're between sizes, you may size down for a closer fit or size up for more comfort.

  • Oversized Fit

    Intentionally voluminous and loose. Most customers prefer their usual size for the intended look, but you can size down for a less dramatic silhouette.
