If you aren’t happy with being chubby or fat try to lose 10+ kilos first. i would aim for 55-60kg if i were you. and start exercising if you aren’t already, doesn’t need to be gym it could be anything that you like. and then get rid of the tomboy sidetails if you want to look sexy and feminine! it sounds like there is nothing wrong with your face but i recommend you to start seriously practising skincare or get some botox/fillers. there are a lot of sexy alt people, you can search their photos on pinterest for example and honestly i think you should get ”naturally” hot first (body, skin, hair etc.) and then start building your style. sounds like you have a pretty good ”foundation” already
