Sizing & Adjustability
Designed with flexibility in mind Iona's lingerie, swimwear and accessories feature adjustable straps and stretch fabrics for a flattering fit. This dedication to adjustability helps you find your perfect size with ease — giving you greater confidence when shopping for lingerie online.
HOW TO MEASURE YOUR LINGERIE SIZE
To find your perfect lingerie fit, use a soft measuring tape and measure directly against your body.
- Bust / Chest: Measure around the fullest part of your bust or chest, keeping the tape level.
- Underbust: Measure directly under the bust where the bra band sits.
- Waist: Measure around the narrowest part of your waist.
- Hips: Measure around the fullest part of your hips. This can be lower down, around your bottom and not necessarily your hip bone.
BETWEEN SIZES? HERE’S HOW TO CHOOSE
If your measurements fall between two sizes, we recommend the following:
- Mesh lingerie: Choose the smaller size. Our mesh fabrics are highly stretchy with four-way stretch and are designed to contour comfortably to your body. Please refer to the product description for specific fit notes.
- Cotton lingerie: Our cotton styles are generally true to size. Select your size based on the main measurement for the piece—bust, waist, or hips, depending on the design. Adjustable straps allow you to customise the fit.
- Lycra: Our Lycra lingerie and bodysuits are super stretchy, soft, and flexible for a smooth, second-skin fit. Lycra swimwear is fully lined for added coverage and offers the same flexibility with a little extra support. Please refer to individual product descriptions for specific fit details.
- Cup Size: Cups are true to size — S = A/B, M = B/C, L = C/D. For extra coverage, consider sizing up. Most styles feature adjustable back bands and shoulder straps for a customised fit. See individual product descriptions or feel free to contact me for extra info.
