I don't have any low pants, and this is because I do not look good in them. I don't care what the fashion trend may be, I'm not going to look like an idiot for the sake of following trends. I do have some mid rise pants, but my top always goes low enough so that they look okay on me. I don't wear them for fashion sake, I wear them because they tend to be very comfortable. I have tried on some of the low pants, and I have to say I have never laughed so hard in a dressing room.
Though it seems to be the younger crowd that loves to wear the low pants, there are some older people who do so as well. I don't think this fashion trend is something that goes by age, but more goes by how you look in them. I think that should be the same for everything, though there are some who insist on wearing things they should not just because it is what everyone else is wearing. This has most definitely the case with low pants. Fashion should be about looking good, not wearing everyone else is wearing. If people realize this, there would be more well-dressed people on the streets today.
On the right body, low pants look very good. On the wrong body, they look ridiculous. It astounds me to see people wearing low pants and tank tops who have no business doing so. Every body is beautiful, no matter what the size, as long as you know how to dress. If you aren't slender, you have to dress accordingly. You can still look sexy, and perhaps the secret to that is knowing what to wear. Just because you see slender women in low pants does not mean you need to wear the same. They may be sexy, but so are you, as long as you know that you are wearing clothes that suit your body, rather than accentuate your flaws.
