A sizer is a soft silicone shape used to help you visualise and compare different size options at home.

Will this show my exact final look?

No. My Dream Size helps with visualisation only. How a size looks can vary with body shape and many personal factors.

How do I choose a size range to start with?

Start with the size closest to the look you want, then compare the sizes either side of it to narrow down your preference.

Can My Dream Size tell me which size to choose?

No. My Dream Size does not recommend a size. It helps you see your options so you can understand your own preference.

How long does delivery take?

Orders are typically produced and dispatched within four days, with express delivery arriving in around five to seven days. Most customers receive their order within nine to eleven days of ordering.

Is the packaging discreet?

Yes. Orders ship in plain outer packaging with no product description on the outside.

Can I return a sizer?

For hygiene reasons, opened sizers cannot be returned. Unopened items in original packaging can be returned under our returns policy.

cc means cubic centimetre u2014 a measure of volume. Our sizers run from 200cc to 1200cc in 100cc steps.

Does a CC number equal a cup size?

No. A cup letter is a bra measurement, and it changes by brand and band. The same CC can look different on different bodies. Compare on yours.

Which kit should I start with?

Start with the range closest to the look you want. Kit A is 200u2013400cc, Kit B is 500u2013700cc, Kit C is 800u20131000cc, and Kit D is 1100u20131200cc. You can also buy one size at a time.

Do kits include a pair of each size?

No. Each kit includes one sizer in each listed size u2014 three in Kits A, B and C, and two in Kit D. If you want the same size on both sides, add a matching individual sizer.

What bra should I use with a sizer?

Use a well-fitting everyday or sports-style bra that holds the sizer centred in the cup. A loose cup lets it shift. A very tight one can flatten the shape.

Is a rice bag the same as a sizer?

No. A rice bag is a rough homemade volume. A sizer is a soft silicone shape with a set cc size, so you can compare the same volumes again. Both are for visualisation only.

Can I try them under my own clothes?

Yes. They are designed to be used under clothing. A fitted shirt or swimsuit usually shows more than a loose top. Take your time at home.

Why does the same CC look different on me than in photos?

Photos are someone else's body. Chest width, skin and tissue all change the look. That is why a comparison on you is the point.

Why can two people wear the same CC and look different?

The number is the same. The body is not. Chest width, existing tissue and how the sizer sits all change the picture. That is why a comparison on you is the only one that counts.

Why is a cup letter not a volume?

A cup letter is a bra fit label, not a measure of cubic centimetres. It moves with the band and the brand. Volume is what a CC number names. A letter cannot do that job.

Why do bra brands size cups differently?

Each brand cuts its cups its own way. A C in one shop can read as a D in another. That is why a letter is a poor target for visualisation. A sizer has a set volume you can try again.

Why is a "full C" in one brand not a number?

"Full C" is a feeling in that brand's bra, on that band. It is not 300cc or 400cc. There is no reliable chart that turns a letter into a volume. Look at the sizer if you want a number you can actually try.

How do I use two neighbouring CCs instead of chasing a cup letter?

Pick two sizes next to each other, such as 300 and 400, or 500 and 600. Try one, then the other, under the same clothes. The difference is easier to see than a letter ever is. We do not tell you which to keep.

What is the sizer for in this decision?

To see and feel a set volume on your body. Not to pick a cup letter. Not to tell you a size. You compare, you notice the look you prefer, you decide in your own time.

Part 2

Choosing & using

How do I choose a size range?

Start with the pair closest to the look you want, then compare nearby sizes under the same clothes and light. That is the clearest way to notice the difference on you.

Can I buy one size only?

Yes. We sell individual pairs only — one CC size at a time — so you can compare step by step without committing to a multi-size kit.

Can My Dream Size tell me what size to choose?

No. We do not recommend a size. We help you understand your own preference by comparing how sizes may look and feel on you.

Does a CC equal a cup letter?

No. A CC is a measure of volume. Cup letters change by brand and band. There is no reliable chart that turns a letter into a volume — which is why comparing on you matters.

How should I place them?

Use a well-fitting everyday or sports-style bra, centre each sizer in the cup, do both sides the same way, then look under a fitted top. See How it works and Guides for the full walkthrough.

Part 3
