Rule one: buy by band and cup
A size "L" has to fit a 36B and a 32F and everything between. It cannot do both well. A sports bra labelled 32F is made for that band and that cup volume. For a fuller bust, this single choice makes more difference than any feature.
Start with your everyday UK size, as long as that size is right. If you are unsure, measure first.
What to look for
| Feature | Why it matters |
|---|---|
| Separate cups (encapsulation) | Controls each breast individually, including side to side |
| Wide underband with hooks | The anchor for everything; hooks allow a precise fit and adjustment as it ages |
| Low-stretch cup fabric | Holds its shape under load |
| High neckline and sides | Limits upward and outward movement and keeps tissue contained |
| Wide, adjustable straps | Spreads pressure; fine-tunes the fit |
| Convertible racerback | A clip or J-hook adds hold for high impact and can be undone for comfort |
| Wicking fabric, flat seams | Reduces chafing |
Wired or non-wired
- Wired sports bras separate and hold firmly, and feel most like a very secure everyday bra. The wire must sit on ribcage all the way round. If it sits on tissue, the cup is too small.
- Non-wired sports bras for fuller cups use a moulded inner frame or dense seaming. They are comfortable for longer sessions and for activities on the floor.
Try both if you can. Preferences here are personal and both types are made to high-impact standards.
Who makes them
These UK-available brands size sports bras by band and cup. Each sets its size range per style, so check the product.
- Panache Sport: wired and non-wired sports bras from a full-bust brand, with cups to H and beyond in selected styles.
- Freya Active: sports range from a brand whose lingerie runs to a K cup.
- Shock Absorber: a long-established sports bra specialist using band and cup sizes.
- Elomi: sports styles designed for larger bands with fuller cups.
- Curvy Kate and Bravissimo: cup-sized sports bras for D cups upward.
High-street chains sell their own cup-sized high-impact bras too, usually with a narrower range in the larger cups.
Choosing by activity
- Running, HIIT, team sports: high or extreme impact, combination construction. See best high-impact sports bras.
- Gym, cycling, hiking: medium to high impact, encapsulation.
- Yoga, Pilates, walking: medium impact, in a softer cup-sized style. Check wires and clasps are comfortable when you lie down.
- Swimming: full-bust brands make cup-sized swimwear on the same principle.
Fitting it
- Fasten on the loosest hooks. It should feel firmer than an everyday bra.
- Lean forward and settle each breast fully into its cup.
- Check for any bulge at the neckline or underarm. If there is one, go up a cup.
- Raise your arms. The band must not move.
- Breathe in deeply.
- Jog and jump on the spot.

Frequently asked questions
What is the best type of sports bra for a large bust?
One sold in band and cup sizes, with separate structured cups, a wide hook-and-eye underband and wide adjustable straps. For high-impact activity, choose a combination design that encapsulates and compresses.
Should a sports bra for a large bust be wired?
It is a matter of preference. Wired sports bras give firm separation and many people find them the most controlling. Non-wired designs with a moulded frame or firm seaming are also made for fuller cups. Fit matters more than the wire.
Which UK brands make sports bras in DD+ sizes?
Full-bust brands size their sports ranges by band and cup: Panache Sport, Freya Active, Elomi and Curvy Kate among them. Shock Absorber and Bravissimo also offer cup-sized sports bras. Ranges vary by style.
