Girls, I love wearing panties. Could you please help me to choose sexy undies?

I'm a guy (23 years) who like to wear girls panties. I've heard that they are more comfortable and come up with various colous unlike boxers. Obviously panties are so cool other than boys underwear. So I'd like to switch to panties soon. Specially suppose to wear them to home instead of tighty whities. Eventhough I like to wear panties i have no idea how to choose the correct size, which one is more comfortable (hi cut or low cut) and even which colour is more sexy? So please help me to choose suitable panties since you girls are experts. (My waist is about 30")
