Underwear Plus Sizing
Inclusive sizing should feel simple. Underwear Plus Sizing is designed to help you find a smooth, supportive fit without compromising on softness. Every piece is made from viscose derived from organically grown bamboo, chosen for a breathable feel and everyday comfort you can wear on repeat.
Plus Sizes in Briefs, Cheeky Underwear, Period Underwear & More
Our women’s plus size bamboo underwear is designed to sit comfortably, stay in place, and feel gentle on skin—no matter your preferred coverage. From barely-there G-strings and cheeky bikini cuts to full-coverage briefs, anti-chafe undershorts, and smoothing shapewear, our range includes every silhouette to suit your style and your day. With clean lines, flexible stretch, and flattering rises across all fits, it’s easy to build a top drawer of dependable plus size underwear in the colours and cuts you love.
For added protection, explore our plus size period and leak-proof underwear, available in three styles and four absorbency levels to support every flow. Made with moisture-wicking bamboo fabric, these supportive pairs help you feel fresh, secure, and confident through long days.

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.
