Dress your age! Fall fashion for 20s, 30s, 40s, 50s

This is the season where anything goes, and these four fall fashion finds transcend the age rules to look chic on just about anyone. “Glamour” magazine pinpoints affordable fashion for every age with clothes that are flattering for all body types.

Fall fashion in your 20s
One of the biggest issues 20-year-olds have is letting go of the collegiate look and embracing an office-appropriate wardrobe. Flip-flops, logo sweatshirts and faded denim should be confined to your weekend wardrobe, if at all. This is the time in your life you want to climb the corporate ladder and be taken seriously, but you still want to have fun doing it.

Our past rules about mixing colors no longer apply. Black, navy, gray and brown can all be worn together, as can stripes and patterns. The trick to mixing your patterns is to stay in the same color family. A wide or narrow belt over your cardigan looks sweet and is a great way to define your waist.

Sweater: Navy cardigan; Banana Republic $68
Shirt: Striped button-down; UNIQLO $29
Belt: Wide belt; Express $50
Skirt: BCBG @ Bloomingdale's $158
Shoes: Patent leather double-strap Mary Janes; Steven by Steve Madden $99
Tights: Opaque black; Wolford

Fall fashion in your 30s
In your 30s, your wardrobe needs to work 24/7 — you should be able to go to the office and look fab and then go out at night in the exact same thing. The new trend is to have your look take you from 10 a.m. to 10 p.m. — no accessory changes necessary.

This fall, a shapely floral dress looks good on everyone and goes just about everywhere. To give the dress a little extra charm, add vintage-y accessories.

Dress: Floral V-neck; Rebecca Taylor $350
Jeans: Seven For All Mankind $165
Necklace: Lee Angel $180

Fall fashion in your 40s
The old rule of keeping hemlines below the knee once you hit 40 has been put to shame. Clearly, you don't want to go too mini (if it feels inappropriate, it probably is), but there's nothing that looks more modern than a great coatdress in a fancy fabric paired with an opaque black tight.

The new shoe style this fall is an oxford-inspired heel — look for a fall fabric like tweed, or patent leather. The delicate balance of masculine and feminine touches also looks great with suits.

Coatdress: Silver coatdress; H&M $60
Shoes: Black patent pumps with bows; Isaac Mizrahi For Target $29
Cuffs: RJ Graziano + Ben Amun
Bag: Silver faux-snakeskin clutch; Devi Kroell For Target
Tights: Black shiny tights; Wolford

Fall fashion in your 50s
If you’re in your 50s, this is the season to invest in a coat that’s anything but boring. A bright red trench is the perfect attention-grabber. A wide-leg jean makes this ’70s-inspired look totally 2007, and it would be just as chic on a 20-year-old as it is on a woman in her 50s.

Top: White ruffle blouse; Gap $44
Jacket: Red patent-leather trench; Michael, Michael Kors $199
Jeans: “Ivy” wide-leg organic jeans; Seven For All Mankind $183
