You can wear and fashion trends, but only if they are given the girl or woman. And that now often observe how plump girls wear tight, tight jeans, highlighting all of its shortcomings, and even increasing them. I like the classic jeans wear, since I wide hips and narrower jeans only accentuate them even more.
No need to blindly follow fashion, fashion for example in the statistics is the most frequently occurring value, and in fact everyone wants to be individual. You just need to have a sense of harmony.
