Men : Taurus, leo scorpio and maybe even libra (just in terms of looks)
Women : I agree with one the answers that says Pisces and Leo.
Leos are so vibrant and always steal the spotlight wherever they are. Also, every leo has their own swag which makes them stand out.
Pisces are just very beautiful in a watery, ethereal way and they are also very creative and have their own unique style which draws attention.
After that I would say, Gemini's and aquarius, and also virgo, cos they are always well put together.
