There’s NO support at all!!! It’s for high impact sport?!? If you go for a very, very slow walk. I do not recommend and if it was possible I would return it but wore it once.

Nice Product
i love this bra
Le (United Kingdom) Used for
i have a very ample bust, like a 34 F but i wear a uk size 10. I love love love the support these bras give i wear a L but they are quite a snug fit. I actually wear two when doing really active workouts and i love the support they provide. For the money they are really great i have like 6 already. However XL is the biggest size so anyone with a larger dress size and bigger boobs may not find these suitable.
Ridiculous sizing
Izzy (United Kingdom) Used for
The quality seems ok but the sizing is definitely not. It feels like I have ordered a bra from ebay from a Chinese retailer, not a Decthlon one. I am size 12 and XL is way too tight, even for my size 10 partner.
Take one size up
Jeanne (United Kingdom) Used for
I ordered a size S as I am generally a UK size 6 for tops. A size S is definitly too small for it.
I would also not recommend if you are planning to wear it in public spaces without a top over it as it doesn't hide nipples.
You get what you pay for!
Great Value
Reem (India) Used for
Good support and very comfortable, immediate difference in the impact to the breasts because of the high quality! Loved it! Waiting for more colours!
Way too small!
Hannah (United Kingdom) Used for
Ordered an XL at a UK size 14, I thought that would be ok... wrong... these come up tiny, worn for a few hours, and I have red marks on my skin, and it was painful... sizing is off for sure...
Great value for money
Kate (United Kingdom) Used for
Really excellent value at such a cheap price. This is a compression sports bra which means it works by squishing your breasts close to your chest and has a flattening effect. I wear it running and find it very supportive. The tricky thing is to find the right size - I’m a small size 8, bra size 28E or 30DD, and usually wear XS in Decathlon clothing, but in this bra I had to get an M. So I’d say it’s probably a bra which works best for smaller and medium-busted women. However if it fits you, it’s hard to find a sports bra which is better value for money.
Good purchase
