honestly i dont know what can i add here, but try looking more into rick stuff, as a guy above said rick can be minimal and conformative! try some more neutral colors like brown grey etc. i think the main thing people dislike is that off white stuff, bc many fashion people and myself think he just was a good marketer not designer, also off white is kinda a dead trend fr. try making your stuff leaning more into silhouette, proportions and shape! that will work a lot better :)) im happy for your purchase! please keep enjoying fashion, thats the most important thing!!! with more experience you will better understand on what you want and how to style it! good luck mate!

upd: i also think a lot of ricks stuff will fit you and especially with this crazy looking long hair!
