I've never had trouble finding what I consider modest dress - knee-length skirts, shirts that cover my belly, jeans that don't show my underwear. Maybe it's a little more work but it's not that big a deal. I honestly don't know why people complain. Sure, there are plenty of immodest clothes out there, lots of stuff I wouldn't wear, but it's not hard to find nice stuff.
Yeah. All that stuff is out there. Land's End, for example, offers jeans in at least 4 heights of rise, to suit almost any figure. They fit, too, according to my wife, who shops there almost exclusively.
For teens, though, it's a tougher deal. They're dealing with peer pressure and want to shop in the stylish stores frequented by their friends. That makes it a little more difficult.
Nor I. My favorite stores include: Chico's, Petite Sophisticate, Kohls, Geoffrey Beene, Van Heusen, Coldwater Creek, etc...
One key to modesty is understanding how clothes fit on your body. A flattering, modest sillhouette on one person would be inappropriate on another woman with different proportions.
The article seems to be critical of immodest fads because there truly is no shortage of modest clothes (even for youts). Chasing fads is rarely worthwhile but they can be fun to work into a basic wardobe of well-fitting, modest pieces. For example, just yesterday I saw a pretty, lacy tank top in a store. The mannequin was shown wearing it with a skirt. Yuck. I would wear it under a blouse with a nice blazer.
As you say, it's not hard - it just takes some thought.
