Bra Size Assistance
With nearly 100 bra sizes in stock to choose from and a selection of more than 30 European lingerie brands, LACE is the big cup bra and bikini fit specialist.
The LACE bra fitters will use a tape measure to establish the band size of the bra. To do this at home, measure the circumference of your ribcage directly underneath your breasts, using a flexible measuring tape. Ensure the tape is horizontal around your body by checking the tape is level in the mirror, or have someone assist you. This measurement must be taken firmly, as the measuring tape has no stretch, and can be taken with or without a bra on.
If you do not have a flexible measuring tape at home, you can also use a string or ribbon and measure against a ruler.
1 Find Your Band Size
|Underbust in cm||63–67||68–72||73–77||78–82||83–87||88–92||93–97|
Note: The above chart is a starting point for establishing your band size. If your measurement is close to another size range, you may wish to try two different band sizes as a starting point. Women in a larger cup or band size may find a smaller, or a more firm fitting band to offer more support.
2 Finding your cup size
To find your cup size, start by assessing the fit of your current bra today.
- The bra cups should contain all of your breast tissue at the front and sides, and underwires should be laying flat against the ribcage, both at the centre front and under the arm. Underwires should not press into delicate breast tissue, and the wire should align with your breast crease; the breast root medically known as the inframammary fold.
- The breast should be lifted into the cups with your nipple in the deepest part of the cup, or where the seams meet. There should be no space or extra fabric at the bottom of the cup, so wiggle the underwire and cup right up underneath your breast.
- When lifting your arms, the bottom of the cup and the underband should remain on your torso, not lifting up or away exposing the bottom of your breast.
After measuring for band size, if you need a smaller band size than the bra size you are currently wearing, you will need to increase the cup size, due to “sister sizing” because not all cup sizes are equal.
For example, if you are wearing an EU 80F and the cup size looks correct, but you need a tighter band, you would need to try a EU 75G, a bra in a sister size.
Cups Too Big?
If the cup looks too big, but the band is too loose, try pulling the band tighter to see if the cup fits better. In a cup size too large, the wires may seem like they go back too far, or there is excess space in the cup.
Some cups may look too large, when instead the style of bra may not be the best fit for you. Bras with full cups or t-shirt bras with stiff padding may have space in the top of the cup if you don’t have a lot of fullness in the top of your breast.
Cups Too Small?
If all of your breast tissue is not contained within the cup, or the wires are not sitting flat against your torso, you will need to try a larger cup size. The cup of a bra will get deeper from 1-2cm depending on the brand, so make a mental note of how much larger in the cup you may need to try.
Bra Fit Tips
It is in our experience that the number one mistake is that many women are wearing bands too loose, and cup sizes too small, so they are not getting the lift and support that they want or need.
It's important to remember that each brand is unique with its sizing and styles, and will fit differently on everyone. The band of the bra offers the most support, approximately 80 - 90%, so be sure the back band is sitting level across your body and is firm. To check, slip off the shoulder straps to see if the band continues to hold firm. The shoulder straps should be comfortable, not too tight, as they only provide 10 - 20% of the support.
