How tight do you wear your suits?

[Torchwatch]

A Speedo style swim brief that fits around the waist and completely covers the ass crack should fit firmly but an Arena style swim brief that rides on the hips and begins to show some ass crack needs to fit more tightly, compressing everything into the space available and gripping the body. Once you minimise a suit and have to add a pouch at the front it doesn't need to be so tight.
