Should I Wear Pleated Trousers or Not?

Hi Antonio, I personally like flat front pants. However, many pants sold in retail store are pleated. What is the purpose of the pleat? For me it only makes a person looks bulky. Also I always have problems in storing my phone and wallets. I like to put it in the front pocket but it is not very presentable as it will bulge out. What’s your point of view? Thank you.
