What goes into a match
The recommendation tool uses the same product details as our Product Database and Finder: product type, what it's used for, padding, closure, straps, back style, material, feel, construction, support, brand, and sizing.
How similarity gets calculated
Similarity comes from how much two products actually have in common. The details that matter most for how a bra feels count for more — what it's used for, padding, closure, and straps carry more weight than which brand made it. Shared feel and construction details add a bit more evidence. Anything missing or unknown never counts toward a match.
| Attribute family | Role in similarity |
|---|---|
| Use cases | High weight; compares practical purpose such as first bra, school, everyday, sports or sensory use. |
| Padding / lining | High weight because coverage preferences can materially change the choice. |
| Closure | High weight; pullover and back-closure products can feel very different in daily use. |
| Straps / back | High-to-moderate weight; adjustable, fixed, racerback and convertible configurations affect use. |
| Feel / construction | Moderate weight based only on shared verified tags. |
| Material | Moderate weight when the published material wording overlaps. |
| Support / type | Moderate weight; helps separate everyday and activity-oriented options. |
| Brand | Very low weight. A same-brand product is not assumed to be the best alternative. |
What a match score isn't
- It's not a comfort rating.
- It's not a quality rating.
- It's not a popularity ranking.
- It's not a claim that two sizes are interchangeable.
- It's not proof the two bras will fit the same body the same way.
- It's not hands-on testing, unless a page specifically says we tested it.
How sizing fits into this
Sizing is a separate, second step. Once you've found products with features you like, the cross-brand size comparison can map your current measurements onto the sizing systems different brands use. That's useful context, but the actual product chart and the 5-point fit check still make the final call.
No paid placement
Right now, nothing here is boosted for affiliate availability, retailer commissions, price, sponsorship, or placement. If that ever changes, it'll stay completely separate from how similarity is calculated, and it'll be disclosed in our Affiliate Disclosure.
Why we're explaining all this
A recommendation tool is only actually useful if people can see what it's optimizing for. Publishing how it works means you — or anyone else — can question it, help improve it, and check our work as the product database grows.
