ASA & British Swimming Guidelines from earlier this year can be found here

As they reference the FINA guidelines and the information we received from the Newburn Meet matches the FINA Press Release I have included an extract below along with links to the original pages on the internet.

"SHAPE – For men, the swimsuit shall not extend above the navel nor below the knee, and for women, shall not cover the neck, extend past the shoulder, nor extend below knee. Furthermore, no zippers or other fastening system is allowed."
