Quick answer: start with the exact product chart
A size label alone does not tell you all of the measurements for a garment. Start with the chart or measurement information on the exact product page, identify whether the values describe your body or the garment itself, and compare only the measurements that the product actually provides. If a value or measurement type is missing, treat it as Not specified rather than guessing.
Body measurements and garment measurements are different types of information. Do not treat them as interchangeable values.
Before you measure
- Open the size chart or measurement details on the exact product page.
- Check whether the chart is labelled as body measurements, garment measurements, or neither.
- Choose one unit for your notes: inches or centimeters.
- Use a flexible measuring tape and record the date, because your notes can change over time.
- Measure over light clothing or undergarments rather than bulky layers.
- Write down only what you measured or what the product page states. Leave unclear fields as Not specified.
If you convert units, use the exact length conversion 1 inch = 2.54 cm. This converts units only; it does not convert clothing size labels.
How to record body measurements
These notes describe general measurement points. They do not create a universal size recommendation. Compare your notes only with a product chart that defines the same measurement.
Bust
Record the circumference at the fullest bust level. Keep the tape level around the body.
Underbust
Underbust refers to the circumference directly below the bust. This guide does not provide a bra band or cup formula. Use an underbust value only when the product chart asks for it and identifies how the value is used.
Waist
Identify your natural waist level before recording the circumference. If a product chart defines a different waist measurement point, follow the product chart's definition for that comparison.
Hips and seat
Record the circumference around the fullest hip and seat area. Keep the tape level around the body.
Torso or body length
There is no universal torso-length method in this guide. Compare a torso or body-length value only when the product chart defines the exact start point, end point, and measurement type. A garment length is not a substitute for a body length.
Body measurements vs garment measurements
How to distinguish body measurements from garment measurements
| Measurement type | What it describes | Where the value comes from | How to use it | Common mistake to avoid |
|---|---|---|---|---|
| Body measurement | A dimension recorded from the person. | Your measurement notes or a body-measurement range stated by the product chart. | Compare your body value with a chart that is explicitly labelled for body measurements. | Do not compare it directly with an unlabelled finished-garment value. |
| Garment measurement | A dimension recorded from the finished item. | The product page or another product-specific measurement source. | Use the measurement points and endpoints defined for that exact garment. | Do not assume it is the body dimension intended for the same size label. |
| Unclear or unlabelled value | The measurement type is not stated. | A chart or description that does not define the value. | Record it as Not specified and seek clarification before using it. | Do not decide from the number alone whether it describes a body or garment. |
Printable measurement worksheet
Use this worksheet to keep your body measurements separate from the measurements and details listed for a specific product. You can print the page and complete it by hand. Nothing entered here is submitted or stored by Sensa Lingerie.
Your body measurements
Record your body measurements
| Field | Your note | Definition or reminder |
|---|---|---|
| Date measured | Record the date. | |
| Units | Inches or centimeters. | |
| Bust | Fullest bust level. | |

| Waist | Natural or otherwise clearly defined waist level. | |
| Hips | Fullest hip and seat area. | |
| Torso / length note | Optional; include endpoints if they are defined. |
Product / garment measurements
Record product-specific information
| Field | Product-page value or your note | Recording rule |
|---|---|---|
| Product name / URL | Copy the exact product name or page address. | |
| Size selected | Copy the exact size label. | |
| Chart type | Body / Garment / Unclear / Not specified. | |
| Chart values | Record labels, values, units, and defined endpoints. | |
| Included pieces | Included / Not included / Not specified. | |
| Materials | Copy only what the product page states. | |
| Construction | Record only explicitly listed construction details. | |
| Closure / strap details | Record explicitly listed features. | |
| Missing information | Use Not specified; do not infer from images. | |
| Personal notes | Optional and kept by you. |
How to read a product size chart
- Confirm that the chart belongs to the exact product you are considering.
- Identify whether the values describe your body or the finished garment.
- Check the units before comparing any numbers.
- Copy the exact size labels and every measurement the product provides.
- Compare the same measurement type with the same measurement type.
- For a length value, check whether the page defines the start and end points.
- Record missing or ambiguous fields as Not specified.
- If two relevant measurements point to different size ranges, seek clarification about the displayed chart instead of creating your own conversion rule.
Size labels and international sizing
Size labels can vary by product and brand. XL, 1XL, 2XL and other labels do not have one universal US/UK/EU measurement conversion. Start with the exact chart on the product page, identify whether it lists body or garment measurements, and compare values in the stated unit.
Inches and centimeters may both appear. If you need to convert a length, use 1 inch = 2.54 cm. Where product-specific measurements are available, use those values instead of a generic clothing-label conversion table.
Compare garment types
Garment names describe general formats, but exact construction, measurements, and included pieces can vary by product. Use this table to identify the details worth checking on each product page.
Product-page checks by lingerie garment type
| Garment type | General format | Pieces | Measurements to check when listed | Included-pieces check | Construction details to verify |
|---|---|---|---|---|---|
| Babydoll | A bodice or upper section with a skirted lower section. | One garment; it may be sold with another piece. | Bust, underbust, waist, garment length. | A brief or thong is included only when explicitly listed. | Cups or underwire, straps, closure, lining. |
| Chemise / Nightdress | A slip- or dress-format garment. | Usually one garment; it may be offered as a set. | Bust, waist, hips, garment length. | Check whether a brief, robe, or accessory is explicitly listed. | Straps, cups, side openings, lining, closure. |
| Bodysuit / Teddy | A one-piece torso garment. | Primarily one piece. | Bust, waist, hips, garment or torso length when defined. | Do not assume accessories or hosiery are included. | Crotch or other closure, cups, straps, lining. |
| Lingerie Set | Coordinated pieces offered together. | Multi-piece. | Measurements supplied for each listed piece. | Record every piece explicitly named on the product page. | Cup or band construction, waistband, garters, closures, lining. |
| Bralette | A bra-style upper-body garment. | One piece; it may be part of a set. | Bust, underbust, cup or band information when supplied. | Do not assume a bottom is included. | Cups or padding, band, straps, closure, lining. |
Product-page checklist
Before choosing a size, check the information available on the exact product page. Use Not specified whenever a field is not provided.
- Chart type: body measurements, garment measurements, unclear, or not specified
- Exact size labels and units
- Bust
- Underbust
- Waist
- Hips
- Garment length and defined endpoints
- Materials
- Construction details
- Closures
- Straps
- Cups or underwire, when explicitly listed
- Lining or gusset, when explicitly listed
- Every included piece
- Missing or ambiguous fields
Included-pieces rule
A piece shown in an image is not considered included unless the product page explicitly lists it.
Included
The product page explicitly names the piece as part of the item or set.
Not included
The product page explicitly excludes the piece.
Not specified
The product page does not explicitly confirm inclusion or exclusion. Do not decide from photography.
What to do when information is missing
- Record the field as Not specified.
- Do not infer materials, construction, included pieces, or measurement type from product images.
- Do not convert a size label into a measurement without a product-specific source.
- Ask for clarification about the information displayed on the product page before using the missing field in a size decision.
After delivery: check the product against its listing
After delivery, compare the item you received with the measurements, construction details, and included pieces listed on its product page.
- Do closures sit in the position shown and described for the product?
- If the product has adjustable straps, do they remain in the position you set during ordinary movement?
- Does the garment length correspond with the design and measurement stated on the product page?
- Do seams, cups, bands, and panels sit in their intended positions?
- Does ordinary movement materially change the placement of the garment?
- Does the package contain every piece explicitly listed on the product page?
If the product differs from its listed measurements, construction, or included pieces, keep the relevant product-page information and contact Sensa Lingerie with the exact product name and order information.
Methodology and sources
General body-measurement guidance in this resource is kept separate from Sensa product information. Product-specific sizes, materials, construction, measurements, and set contents come from the current individual product page. Product information may change, so the individual product page remains the source of truth for the item currently offered.
Photos alone do not establish included pieces, materials, construction, or measurement type. Missing or ambiguous fields are not guessed.
Editorial policy: Unknown / Not specified is preferable to inference.
