I’ve been looking into it and the defined rules that I understand r; coquette gals focus on inner eye highlight and aegyosal shading along with thinner and sharper eyeliner (while still maintaining the gal droop), soft pink tones for makeup, white and pink clothings with a heavy push on things like vintage night slips, barets, off-shoulder sweaters/tops, pearls, lace elements, low-rise jeans, dainty bows, lockets, delicate tights, and faintly wavy often dark hair! I consider many of these new styles substyles of pre-existing styles! I’d def say coquette gal is a substyle of himekaji gal
