I bought a bunch of bras from MP and this one runs significantly small, I would size up. Quality-wise the material is quite simple. Good thing is the length of the bra - it is quite long and can be worn as a top 

Gorgeous sports bra, really beautiful and makes my flat chest looks nice. I ordered a S and it fits perfectly. I was a bit worried reading the reviews that said order a size up, but if you have a small chest like me it fits perfect in your normal size.

This sports bra is amazing! It offers great support, looks stylish and stays in place. I like that it is long and is more like a crop top so when the workout gets sweaty, you don’t feel awkward taking your top off and just wearing this! Definitely recommend!

Absolutely love this bra, its so support for whatever training I decide, whether it's going for a run or in the gym. Would highly recommend!

This sport bra looks so lovely but not practical no support at all. The straps are not strong to hold the chest
