True size and the fabric is amazing. Definitely worth buying from oh Polly.
I love love this but didnt look good on me had to return because i have a big bust and my breast were not supported
I ordered a size 4 and was so happy with results.It was my 21st and I left heads turning I’d highly recommend getting it.
