Is this petty of me :/?

i want to stand out more and be more unique, so ive basically been changing little bad habits of mine. one of them is dull fashion sense, i used to wear just tee shirts and jeans every day because i was too scared of what people thought of me to wear anything else. but ive been breaking out of that to gain more confidence and whatnot, and one of the articles of clothing ive been wearing often is rompers. i really like them a lot and for a while i felt really special in them because no one else wore them, sorry that sounds really lame. but now some of my friends have started wearing rompers constantly and theyre like trying to make it into some kind of romper group or something and i feel like part of the "special"ness has been ruined for me. is this normal or am i being like really petty about it? im not going to say anything to them but im just kind of disappointed because that was kind of my thing for a while.
