The notch lapel has a separation between the collar and lapel, usually at 45 degrees. You will see this lapel most often on suits and sportcoats.
The lapel in the peak lapel rises up and above the collar tip. This lapel is seen on double breasted coats, but we are seeing them on two button side vented suits now.

Lapels seem to be getting narrower – going from 3 1/2” to 3 1/4”. Coats are trimmer in the body and a little shorter. Trouser legs are getting a little more narrow from the knee down. To complete this “Mad Men – 1960’s look, we are seeing some thinner ties too.
