How to choose the right lingerie size and avoid mistakes

June 15, 2026

Size Guide

It can be difficult to choose lingerie sizes based solely on your usual clothing size. By considering the stretchiness, material, shoulder straps, silhouette, and set contents, you can make a more informed decision even when shopping online.

Order of checking sizes

Listed sizeEven for free-size items, the recommended body type and elasticity vary by product.
ElasticityLace, mesh, and polyester-based fabrics affect the fit differently.
Shoulder strapsAdjustable designs tend to alleviate concerns about the neckline and shoulder area.
LengthThe appearance changes significantly between babydolls, bodysuits, and dresses.

Don't just aim for "perfect fit"

Since many lingerie items conform to the body, even slight elasticity or strap placement can change the impression. If you are choosing for the first time, prioritize items with adjustable features, clear shapes, and multiple photos for peace of mind.

If you have concerns about your bust, waist, or hips, first check the stretch of the material and the shape of the product.

Also check the contents of sets

The contents included vary by product, such as a top and shorts set, with stockings, or with ribbons. In addition to the size, please check what is included in the set before purchasing.
