Hi, just received my first pair of Fendi t-strap heels. While they fit and I like them the heel just seems so high to me. Bluefly listed as 3.5 but more like 4" to me. I'm already close to 5'8 so feel very tall. My question is how high to most of you go with heels. I know most probably do wear 4" but how tall are you to begin with? Will I get used to these?
