Weird body shape??

Issy
Okay so just before I start I don't agree with labelling people but I'm gonna use these terms so ya'll know what I mean generally

I am tall and what I believe is considered 'plus sized' but not in the way I think is hot or viewed as attractive. I have fairly big boobs but no ass and big thighs and belly. I barely have a waist and my belly sticks out. I realise that some of these things may be with age and as I haven't finished puberty so my body is still changing but I'd really like some tips on how to pull off fitted clothes and general style confidence. Thanks
