I am big (!!) and I will wear jeans as long as they are comfortable! I buy them in sizes big enough to fit properly, and in a style that actually sits on my waist, not hips, so I don't suffer from that horrible 'muffin-top'! I wear them with all sorts of tops, depending on the occasion and weather, but the top is always long enough to never risk showing any flesh between top and jeans (yuk!). I can't see me stopping wearing jeans unless and until I can't fasten them due to fingers not working properly!
