Editors Notes

Speedo has a long and impressive history dating back to the early 20th century when the company was created in Australia in response to a growing beach culture down under. Since the birth of the brand, Speedo have always made headlines thanks to the style and the performance of their swimwear.

Speedo dominate competitive swimming with a staggering history in relation to the Olympic Games. Since the 1950s Speedo have had a powerful connection with Olympic athletes, culminating in the Beijing Olympic Games where 92% of all swimming medals were won by athletes wearing Speedo swimwear.

Speedo use the ground-breaking technology they develop for athletes in their commercial ranges to give you a competitive edge and a more enjoyable swimming experience. For example, the Endurance range is developed to be chlorine resistant so you won’t have to replace your swimwear time and again.

Q & As

Rated 4.6 out of 5 by 34 reviewers.
Rated 5 out of 5 by speedo girls medalist swimsuit Very flattering cut. It seems to makes every little body, no matter what shape, look athletic! 05 February 2014
Rated 4 out of 5 by Sizing Fantastic swimsuit, washes well and stands up to repeated chlorine and use. The sizing is the only issue but then children really do come in all shapes and sizes. The sizing on the tag is slightly better as it lists the height measurement as well. Size 30 equates to 140 cm. So chest measurement doesn't necessarily work. My daughter is a tall 9.5 year old (141cm) with a 25 cm chest and I now need to order her the 32 as it is a tiny bit short so rubs in long swim sessions. 25 April 2013
Rated 4 out of 5 by Great swimming costume, nice bright colour Bought the electric blue Speedo Medalist suit for my 10.5 yr old daughter but did find the sizing incredibly difficult - so thought I would write this review to help others. My daughter is 137cm tall so quite small for a 10.5 yr old. She is slim no hips etc. Her measurements are 25cm chest, 22.5 cm waist and 25cm hips. I bought 30cm costume thinking this might do based on other reviews for children about the same age. We will keep the costume as my daughter loves it - fantastic suit in the bright blue and lovely shape. But it is a little big. Mostly a bit baggy around lower front and slightly all over. But not much. The next size down would have been ideal but this one is wearable and should last for a while. I guess 'proper' swimming costumes are designed to be worn tight hence the recommended measurements. Loved the click and collect service to my local Waitrose too. Arrived the next day! 03 April 2013
Rated 3 out of 5 Sizes confusing I've ordered the wrong size using the John Lewis size chart. Rather than have them sized by age they are sized by chest in inches and the John Lewis chart shows chest in centimetres. I have ordered the 26" which equates to 10 year old girl on your chart but now it has arrived I see that this is for an 8 year old. Very annoying and a waste of everyone's time. 06 March 2013
Rated 5 out of 5 by Fits perfectly and looks Great Great light weight costume that fits beautifully, plus my daughter loved it. 25 November 2012
Rated 4 out of 5 by a good product!!! This is very comfortable, soft and fit nicely for my 12 year old niece. I strongly recommend it. The only thing she expects more is inner bra cups. If you need removable cups, this is not for you. 25 October 2012
Rated 5 out of 5 by great though not perfect size for my daughter but fitted not leaving her too exposed and she will grow into the little folds 28 September 2012
Rated 5 out of 5 by my first John Lewis online order I bought this swimsuit online as I was too busy to go into one of the stores that week. The online experience was very positive. It was very smooth and effortless from finding the item I wanted all to way to check out and delivery. I will most definitely be shopping online with John Lewis in the future. 27 September 2012
