My International size Tumi carry-on is split into two halves - one flat with with a cover, the other looser and with indents for the handle.

Anything which creases goes folded in the flat half - Shirts, dress trousers, polo shirts whatever. Anything else gets rolled up in the other half along with shoes and toiletries (underpants, socks, shorts, casual clothes incl. gym kit, etc.).
