It is easy to wear the wrong bra size for years. Finding the right one takes a tape measure, two numbers and about two minutes.
What you need
- A soft tape measure
- An unpadded bra, or no bra
- A mirror, so you can keep the tape level
How do I measure my bra size?
- Underbust. Measure directly below your bust, where the band of a bra sits. Keep the tape snug and level, and breathe out naturally.
- Bust. Measure around the fullest part of your bust. Let the tape rest gently, without squeezing.
- Hips (for your bottoms). Stand with your feet together and measure around the fullest part of your hips.
Round to the nearest whole centimetre. Our size guide works in cm and inches.
How do I read the size chart?
Start with your underbust: that gives your band size. Then find your bust measurement next to it: that gives your cup.
The Phoenix Balcony Bra is underwired and sized by band and cup:

| 70B | 68-72 | 84-86 | 85B | 32B |
| 70C | 68-72 | 86-88 | 85C | 32C |
| 70D | 68-72 | 88-90 | 85D | 32D |
| 75B | 73-77 | 89-91 | 90B | 34B |
| 75C | 73-77 | 91-93 | 90C | 34C |
| 75D | 73-77 | 93-95 | 90D | 34D |
| 75E | 73-77 | 95-97 | 90E | 34DD/E |
| 80B | 78-82 | 94-96 | 95B | 36B |

The June and Pixie bralettes are wire-free and come in XS to XL. The same two measurements point you to your size in the size guide.
In every set, you choose your bra and bottom sizes separately.
How should a bra fit once it's on?
- The band sits level at the back and feels snug on the loosest hook. It does the supporting, not the straps.
- The cups hold you without gaps or spilling over the top edge.
- The wire (on Phoenix) follows the base of your bust and lies flat against you.
- The straps stay in place without digging in. A strap that slips usually needs a small adjustment, not a new size.
What if I'm between sizes?
For a balcony bra, let your underbust lead and choose the band that feels snug, not tight. For a bralette, the softer fit is forgiving, so choose the size that matches most of your measurements.
