A smart clothes system can include: a transmitter including a source loop, a first transmitter resonator surrounding the source loop, and a second transmitter resonator surrounding the first transmitter resonator; and a receiver including a load loop spaced apart from the source loop, a first receiver resonator surrounding the load loop, and a second receiver resonator surrounding the first receiver resonator. The transmitter can be configured to face the receiver such that it transmits power and receives data. The source loop, the first transmitter resonator, and the second transmitter resonator can be disposed on the same plane as each other, and the load loop, the first receiver resonator, and the second receiver resonator can be disposed on the same plane as each other.
