Great quality and washes well!
Good quality and fit and most importantly washes well - my daughter has used this every week for swimming lessons and it still looks new. We only got a new one as she had a outgrow the old one

Best swimming costumes
11-12 years for my long 10 year old had to be exchanged to a size 13-14 years which fits her perfect. One of her best swimming costumes and will be buying more.

Nice quality and fit, Size up
Purchased for swim lessons. Runs a size smaller than standard UK sizes, so size up for a better fit. Washes well, comfortable fabric. Purchased on special and am usually happy with Speedo products…not the same quality as say 20 years ago but good enough. Prices have come down considerably, so not complaining.

Great costume
I heard that many parents make the mistake of buying blue costumes which is the worst colour for water so for safety reasons I was determined to get a bright colour. This is a great costume, good quality, nice thickness, good swimability, has washed fine. Good bright red colour, comfortable and good value for money.

Tiny sizing
Tiny sizing, so had to return. Definitely go up at least 1 size. Good quality product if it fits!
