Fit Fully Yours Size & Fit Guide

← Fit by Brand

Choose Fit Fully Yours bras and panties using the brand’s cup comparison and hip measurements in inches. Check the exact label on older styles, and use separate fit guidance for molded, wireless and strapless bras.

US band numbers only. Keep your fitted US band number when comparing cup labels: a 34 band stays 34. Cup letters can change between brands. Always choose a size offered on your exact product.

Fit by product & style

Crystal Smooth, Maxine & other bras

Use the brand cup column below. Some legacy product options show E alongside DD; ask us to confirm the exact style if both appear. Do not apply UK cup lettering to these product labels.

Strapless & wireless designs

Test a strapless style with straps removed; for wireless styles, check band stability and full cup containment.

Panty label variants

Use the hip chart matching the label. A product offering 1X/2X/3X may need a label check before applying a chart labeled XL/XXL/XXXL.

The manufacturer’s cup column uses DD and then F. Our older product labels may differ; contact us when both DD and E appear for the same style. Panty hip measurements are independent of bra cup.

How to measure & check fit

Use a soft tape. Measure the fullest part of your bust, your natural waist and the fullest part of your hips, keeping the tape level without pressing into the body. Tables labeled body measurements refer to you, rather than the garment laid flat.

For bras, measure snugly directly below your bust and around the fullest bust in an unpadded bra. These measurements help our team assess a starting size; band methods and cup construction differ by style.

  • The band should sit level and feel secure without restricting breathing.
  • Cups should contain the bust without spilling or gaping, and wires should sit around breast tissue comfortably.
  • Adjust straps without using them to compensate for a loose band. Check fit while sitting and moving.
