Why the cut matters

Wetsuits work best when their pattern follows the diver’s proportions. A women’s cut can use a different relationship between the bust, waist, hips, shoulders and torso length. Simply choosing a smaller men’s size may leave one area too tight and another loose.

That does not mean every diver needs the same labelled cut. Your measurements and comfort are the useful checks. You should be able to breathe fully and move your shoulders and hips without painful pressure, strong pulling or large gaps.

Measurements to take before choosing a size

Use a flexible tape, measure without bulky clothing and follow the brand’s own instructions. Keep a note of the units you use; do not compare centimetres with an inch-based chart.

  • Height and weight: useful starting references, but not enough to decide fit on their own.
  • Bust or chest: measure around the fullest part, keeping the tape level.
  • Waist: use the point specified by the size chart rather than assuming a trouser waistband measurement.
  • Hips: measure around the fullest part.
  • Torso and leg length: follow any additional measurements requested for that model, particularly for a two-piece suit.

If you sit between sizes, ask for fit advice rather than automatically sizing down. A very tight suit is not a substitute for the right pattern. GEDDON’s final size chart and fit guidance will be released after sample development; the current waitlist asks for a preferred size, not a final fit decision.

Check breathing, movement and seals together

When assessing a suit, check that the hood and neck sit comfortably, the shoulders move freely and the jacket overlaps the trousers as intended. Look for excessive folds or voids around the lower back and underarms, and pulling through the crotch or chest.

Fit assessment should follow the maker’s instructions. With an open-cell suit, that includes the correct donning method and suitable lubricant where required. Our open-cell wetsuit guide explains the difference between an unlined neoprene interior and a fabric lining.

Choosing thickness for your diving

Choose thickness around your conditions, time in the water, activity level and individual experience. There is no separate universal temperature rule for women’s suits, and no single millimetre figure guarantees comfort for every diver.

GEDDON’s proposed collection includes Prawle 5.5mm and Start 7.5mm. Read the 5.5mm versus 7.5mm comparison for the practical trade-offs in insulation, bulk and buoyancy. Confirm unfamiliar equipment choices with a qualified local instructor or dive professional.

The planned GEDDON women’s collection

The women’s collection is being developed around a dedicated cut with the same considered details as the wider GEDDON range. Proposed features include an integrated hood with a reflective crown, a sternum loading pad, reinforcement at the knees and elbows, and an open-cell interior.

Moor combines olive, kelp and granite tones; Kelp uses warmer browns and olive; Night brings near-black tones and muted rings. The images are concept visualisations. Final fit, construction, size and colour availability will be confirmed through sample development and before launch.

Join the First Edition waitlist

The First Edition is planned as 100 individually numbered suits, 001–100, from £449, with shipping planned for spring 2027. Choose “Women’s” as your preferred fit, add your current size and thickness preference, and select a colourway—or “Not sure”.

There is no payment to join the waitlist. It is an expression of interest, not a suit reservation or allocation of a number. We will share launch news and information about deposits as the collection progresses.
