More ways to find your perfect fit.
Ever wonder why some Sunsets swim tops are labeled with more than one bra size? It’s intentional.
Sister sizes are different band and cup combinations that share a similar cup volume.
That's why some Sunsets tops are labeled with more than one bra size we've already done the sister-size math for you.
Let's Talk Sister Sizes
Sister Sizes are different band and cup combinations that share a similar volume. For example, 36E, 34F and 32G are sister sizes. While the letters are different, the cup capacity is designed to accommodate a similar bust volume.
That’s why select Sunsets tops combine sister sizes into one thoughtfully designed swimsuit tiered size.
We Do the Sister-Size Math for You
With traditional bra sizing, finding a sister size means adjusting the band and cup together.
If you go down in the band, you go up in the cup. If you go up in the band, you go down in the cup.
At Sunsets, we’ve already grouped compatible sister sizes in our E–H cup styles, so you don’t have to figure it out yourself.
For example:
36E = 34F = 32G
If you normally wear any of these bra sizes, you can shop the 36E/34F/32G Sunsets tier size.
Why We Designed It This Way
Swimwear should fit you, not the other way around.
Our sister-size system allows one thoughtfully engineered swim top to accommodate multiple bra sizes with similar cup volume, while adjustable features help you fine-tune the fit to your body.
Your cup volume stays consistent. Your fit becomes more flexible.
