Where's the stretch

No, I don't recommend this

Wanted a no nonsense swim suit for fitness. What a pain to get on, seems the lycra had been dialed down in the fabric mix. A real struggle to get on due to lack of flex. Once on it's OK, saggs with the weight of water in parts, and the leg opening uncomfortable for the same reason, no flex. Poor fabric quality for the price.

Nice swimsuit, short body - need to order size up

Bought a 10, because I am a 10 in everything M&S sell, but although it was perfect around the hips and legs, it came up very short in the body. Ordered a 12 which is perfect in the body but slightly baggy around the legs and hips.

Perfect

Yes, I recommend this

I had searched for along time to get this fabulous swimsuit in my size. It is so good I tried to order another one as I swim every day. Unfortunately it was out of stock, hoping to receive an email telling me back in stock in my size. It’s perfect fit, chlorine resistant-what’s not to love

Comfortable, good fit

Yes, I recommend this

Bought this for my twelve year old daughter and she loves it - really comfortable and well-made. As always with Speedo, they come up small so had to go up a size or two.

Great fit and support

Yes, I recommend this

This is great for a bit of compression and support around the upper thighs which is why I purchased it.
