i would recommend the classic big top + small bottom or small top + big bottom combo in your outfits! it's very easy and it can be translated into any style!!
just try to not wear tight clothing in both top and bottom as it can be uncomfortable and trigger body dismorphia in the worst moments :(
i would use the oversize trend we've had in the last few years on my advantage :p ppl no longer expect girls to show her figure at all times, so you can be comfortable while still looking cute. you can try to look for those kind of items at the stores or search for inspo on pinterest ! a lot of grunge and emo inspo have that kind of clothing (ofc, if oversized is your style!)
oooh ok i reccomend going 2 a local thrift store or a hot topic or spencerz 4 more emo leaning stuff/band teez also i reccomend finding clothez in a bigger size 2 hide stuff that makez u dysphoric hope thiz helpz X3
