They say no pain, no gain. And when it comes to fashion, that’s usually the case. A tiny waist? That’ll require a corset so tight you can barely breathe. Long, skinny legs? Step into stilettos so high your dogs might literally start barking. Now the good news: Throw it all out the window. With Rachel Pally’s fall line, you’ll look good and feel good. She may have long been a purveyor of that drapey, jersey sort of shapeless stuff, but her latest collection features tailored, more diverse pieces — something appropriate for almost any occasion and every body type. A day of errands? The pocket-front hoodie in colors like peacock and scarlet is effortlessly sexy. A lunch with pals? The ’70s dress in mustard or orange is a real standout. Having a fat day? The full skirt hides what you hate and accentuates what you love. And for your next hot date? The long-sleeve button dress is downright perfect. The only pain involved? Deciding between so many killer pieces. Available at Dress, 2271 Chestnut Street, between Pierce and Scott Streets (415-440-3737); Behind the Post Office, 1510 Haight Street, at Ashbury Street (415-861-2507).
