Chicer is derived from the word "chic" (from French *chic*, meaning stylish or fashionable) and the suffix "-er" (meaning one who). The term "chicer" refers to someone who is more stylish or fashionable than others.
Think of someone who is 'more stylish' ('chic') — the '-er' indicates a person who has that quality. This helps you remember that 'chicer' means someone who is more chic.
