For even more everyday fits, you can still find our wider women's underwear range.

SHOPPING MADE RELATABLE
Boody is committed to making your shopping journey as comfortable as our products.
From your feedback, we know it helps to see our pieces on someone who represents your shape and size. That’s why we’ve made it easier to shop for a more diverse range of body types. This isn’t a stock filter - it’s about visuals. We’ll display models across Small, Mid, and Plus size groupings, and you can always select non-model images too.
A style may still be available in your size, even if we haven’t yet photographed it in your selected size, so we recommend checking the product detail page or using our size filter to be sure.
It’s not perfect yet, but we’re listening to and learning from our community, and are committed to investing in more diversity in model shapes and sizes.
