Hello Seamless Lover, 

Thank you for your question, It sounds like you may be between sizes, which can make the decision a little less straightforward than we may have hoped. We will do our best to guide you based on the fit and structure of each style.

For the Bare Longline Bra, one of our most popular pieces, we suggest trying the size 8C. This size should be right according to your measurements.  We find this bra works well under t-shirts because the longline silhouette and smooth cup shape are designed to create a clean lines under clothing. And you are supported by thoughtful mesh construction and structured stitching.

For the Nano Underwire Bra, we would recommend the 10B. This style starts at a size 10 band size, so while the band is slightly larger than the 8, the cup volume remains the same due to sister sizing.  The adjustable back allows you to customise the support, and the soft cup offers a more natural shape and feel.

If you are looking for something without underwire, the Nano Plunge Bralette could be a good alternative. It is designed to provide support through the back band while offering a more relaxed, free-form fit. In this style, we suggest a size small.

With warmth, Primary
