Boux Avenue is a UK lingerie brand offering both core everyday styles and fashion-led designs. Fit can vary slightly between collections (especially between moulded, plunge and balconette shapes), so it helps to confirm your measurements and then check fit at home.
Boux Avenue knickers are commonly labelled using UK dress sizes. Use this chart to compare UK sizes with common international equivalents.

| 8 | 36 | 36 | 40 | 4 | 8 |

Boux Avenue bralettes and crop styles are often sold in alpha sizing (XS–XL). This table shows the UK size ranges typically grouped into each alpha size.
| Alpha Size | UK Size Range |
|---|---|
| XS | UK 6 |
| S | UK 8–10 |
| M | UK 12–14 |
| L | UK 16–18 |
| XL | UK 18–20 |
If you are fuller-busted and between two alpha sizes, the more supportive fit is usually achieved by sizing up for depth and comfort.
Boux Avenue uses a UK band-and-cup sizing system, similar in structure to many UK lingerie brands.

Q: Does Boux Avenue sizing run true to other UK brands?
A: Boux Avenue uses UK band and cup sizing, but the fit can vary by style (especially between moulded cups and non-padded cuts). If you are unsure between sizes, keep the band secure and try the neighbouring cup size first. To compare across UK brands, use our
Bra Size Converter.
Q: What if the band feels too tight or rides up?
A: A new band should feel firm on the loosest hook. If it rides up, it is usually too big. If it feels uncomfortably tight, confirm your underband measurement and consider sister sizing (for example, 34F to 36E) while keeping cup volume similar.
Q: How do I choose a bralette size at Boux Avenue?
A: Boux Avenue bralettes are often sold in XS–XL. Use the bralette chart above to match your usual UK dress size range, and size up if you are between sizes or want a more comfortable fit through the bust.
