Yes, they can have a creative flair for design and come up with some fabulous outfits. If this is the case, I'm not sure if we should let them into the women's club any more. If not, consider a new eating plan and exercise routine. If you're practicing belly dance once a week, either double the time you practice, or fit in another session each week. Throw them out.
Weight means nothing.
That's why I said look at the clothes sizes that are appropriate for someone of your height. You could go down 2 sizes in clothing and stay the same weight or even put on weight due to the fact that muscle weighs much more than fat. By exercising and eating right, you'd change the balance and have more muscle than fat. The scales will be telling you you're getting nowhere, but in reality you're on the road to being fitter and more healthy. It's just plain unnecessary.
