What are you sizing?
Choose the product type closest to what you are shopping for.
One source of truth
How sizing works on CherryAffairs
The guide explains. Filters narrow. The product page confirms.
Narrow the catalogue
Use grouped filters such as Wearable Fit and Insertable Length to reduce the choices.
Check the exact item
Review the actual variants, manufacturer measurements and size-chart image before ordering.
!
Do not choose from the filter label alone
Broad groups make browsing easier, but brands and product designs differ. The exact product page remains the final reference.
Lingerie & costumes
How to Measure for Lingerie and Costumes
Your normal clothing label is only a starting point. Measure yourself, then compare those measurements with the chart displayed inside the exact product’s specifications.
Measure around the fullest part while keeping the tape level.
Measure directly beneath the bust. This matters most for bras and structured tops.
Measure around the narrowest part of your torso without pulling the tape tight.
Measure below the natural waist where lower-rise garments sit.
Measure around the fullest part of your hips and seat.
Especially useful for bodysuits, costumes and garments with limited vertical stretch.
| Product type | Measurements to prioritise | Check on the product page |
|---|---|---|
| Bras and adhesive bras | Bust and underbust | Band, cup and regional-size conversion |
| Babydolls and chemises | Bust, then waist | Stretch, cup range and adjustable straps |
| Bodysuits and costumes | Bust, waist, hips and torso length | Garment cut and vertical stretch |
| Panties and briefs | Waist and hips | Rise and stretch |
| Bodystockings and hosiery | Hips, height and stretch | One-size range and material elasticity |
| Men’s underwear | Waist | Pouch design and brand-specific fit |
A combined range, not proof that the garment fits every body within both labels.
A manufacturer-defined measurement range. It does not mean universal fit.
A separate extended range. Always check the displayed chart.
Plus-size groupings that vary substantially between brands.
How the filter works
Wearable Fit is a broad discovery tool
It groups products according to the actual clothing sizes stored on each product. It does not replace the brand-specific chart shown on the product page.
!
Check the chart before ordering
Brand sizing varies, and intimate products are subject to hygiene restrictions. Compare your measurements with the exact chart shown on the product page, or contact us before ordering if the fit is unclear. Review the Returns & Warranty Policy for the current terms.
Insertable toys
How to Read Insertable Length, Width and Diameter
Compare insertable length together with width, maximum diameter, shape, taper and flexibility. Total length alone rarely tells the full story.
The full product from end to end, including handles, bases or controls.
The portion intended to enter the body. It may be shorter than the total length.
The straight distance across the product at the measured point.
The distance around the product. Approximate circumference equals diameter multiplied by 3.14.
The widest insertable point, which may matter more than average shaft width.
A gradual taper or flexible material can feel different from a blunt or firm design of the same dimensions.
How the filter works
Insertable Length groups exact product measurements into broad bands
The product metafield stores the manufacturer-provided measurement. Search & Discovery then groups those values to make comparison easier.
XSUp to 8 cmCompact
S9-12 cmShort
M13-15 cmMedium
L16-18 cmLong
XL19-22 cmExtra-long

Quick converter
Diameter and circumference
Use this only as an approximate conversion. Confirm the manufacturer’s exact specification.
Chart converter
Centimetres and inches
Useful when your body measurements and a supplier size chart use different units.
Important: These bands make products easier to compare. They are not experience-level or comfort guarantees.
Masturbators
How Masturbator Size and Canal Length Are Measured
Manufacturers may report overall length, internal depth or usable canal length. Read the product specifications before comparing two products.
Usable canal length
The internal depth available for use. This may be shorter than the external product body.
Opening and stretch
Opening width, sleeve elasticity and texture affect fit differently from length.
Open or closed end
Open-ended sleeves can accommodate length differently from closed-ended products.
Suction and pressure
Adjustable air, pressure or tightness can matter more than the outside dimensions.

How to use the existing filter
Your Insertable Length filter groups the exact manufacturer measurements stored on each product. Treat it as a practical comparison tool, then confirm whether the listed value means internal depth, usable canal length or another measurement on the product page.
Rings & wearable toys
How to Size Rings, Harnesses and Wearable Toys
Clothing labels are not appropriate for every wearable product. Fixed rings, stretch rings, harnesses and wearable vibrators each use different fit information.
Inner diameter
Use the opening measurement, not the product’s outside width.
Material and maximum stretch
Check the manufacturer’s recommended fit range and do not assume every elastic material stretches equally.
Waist and thigh range
Look for minimum and maximum adjustable measurements.
Adjustability and placement
Check straps, magnets, garment compatibility and intended body placement.
Internal dimensions
Confirm internal length and diameter rather than relying on the overall product size.
Choose adjustable first
An adjustable design is usually easier to assess when your exact fit is uncertain.
Condoms
How Condom Nominal Width and Fit Work
Nominal width is the condom’s flat width. Different brands can use different marketing labels for similar measurements.
Nominal widthFlat width of the condom
It is not the same as diameter or circumference. Always check the exact package or product specification.
Common questions
Size and fit questions
Open a question for the practical answer.
Should I use my normal clothing size?
Use it only as a starting point. Measure yourself and compare those measurements with the size chart displayed on the exact product page. Brand sizing can differ substantially.
What does One Size mean?
One Size means the manufacturer designed the garment for a stated measurement range. It does not mean universal fit. Check the size chart shown on that product page.
What should I do if I fall between clothing sizes?
Prioritise the least flexible or most structured area of the garment, then review the product's material, stretch and adjustment features. Contact us before ordering when the chart or fit is unclear.
How do I measure myself for lingerie?
Measure your bust at the fullest point, your natural waist at the narrowest point and your hips around the fullest part. Some bras also require an underbust measurement, while bodysuits and costumes may require torso length. Compare your measurements with the chart displayed on the exact product page.
Is total length the same as insertable length?
No. Total length includes the entire product. Insertable length is the portion designed to enter the body and may exclude a handle, base or control section.
Is width the same as diameter?
Sometimes, but not always. Diameter describes the straight distance across a circular section. A manufacturer may use width for an irregular or non-circular shape, so check the diagram or specification context.
What insertable length should a beginner choose?
There is no universal beginner measurement. Length, maximum diameter, taper, shape, flexibility and intended use all matter. Use the filter bands to compare, not as a comfort guarantee.
How do I choose dildo or vibrator size?
Compare insertable length, maximum diameter, shape, taper and material flexibility. Do not choose by total length alone because part of the product may be a handle, base or control section.
Where is insertable length shown?
Open the product page and check Specifications. Where the manufacturer provides an insertable measurement, it is displayed there and used to place the product into the relevant Insertable Length filter group.
How are masturbator dimensions measured?
Manufacturers may list the overall product length, internal depth or usable canal length. Check the exact wording in the product specifications before comparing products.
Where can I find the exact lingerie size chart?
Open the product page and expand Specifications. Products with a supplied chart display the brand-specific size-chart image there.
Can I return an item if the size does not suit me?
Intimate products are subject to hygiene restrictions. Review the Returns & Warranty Policy before ordering and contact us before purchase if the size information is unclear.
