Marvell Lane Sizing

We no longer supply the sizing measurements for our bikini tops and one pieces because depending on how our customers measured themselves, sometimes they would order the wrong size.

We often find women are wearing the wrong bra size, so before purchasing we encourage you to try our e-Fitting service or if you've recently been professionally fitted, then just shop your bra size.


Try our e-Fitting service. Simply click on this link and complete the form.

We endeavour to answer all customer emails within 24 hours business days.

Check our 'How to measure' page to see what we need from you so we can provide recommendations straight away. Don't worry if you don't have a tape measure - we can still help you. Remember: the more information you provide us, the better we can tailor our recommendations.

Size & Style Advice

Each product description section has some sizing and style advice. We recommend you read this prior to purchasing, especially for our one pieces and style recommendations for our tops. If you have any questions then just reach out:

Sister Styles

Can't find your size? Perhaps you can shop your Sister Size. What does this mean? Check out our information on Sister Sizes here. Note, we only recommend you shop your Sister Size for tie-back styles.

Still have questions? Just send an email to or try our e-Fitting service.

International Customers

Got a favourite bra with an international size? No problem! Check out our International Size Conversion Chart to find your size. Still not sure or can't work it out? Send an email to or try our e-Fitting service.


Fact: Sizes vary across different brands.

We deliberately do not supply the measurements for our tops because if a customer makes a mistake when measuring herself, this can lead to the wrong size top being purchased. Instead we offer an e-Fitting service. 

Check your size in our products before purchasing and save yourself the possible hassle of exchanging it for another size. There is nothing more satisfying than nailing your size first time!
