Believe it or not, your bra can instantly make you look taller, slimmer, and younger (or not) argues Karen Phillips, of online shopping , Jane.com . Wearing the wrong bra is not only uncomfortable (as any woman who has had to spend a day at work with bra straps slashing her shoulders will know very well). As a result, your clothes don't hold well and you look slumped. And, it makes you look 10 years older.

You love fake jewelry

Even if large fake jewelry gives you a little bohemian air, they go out of style quickly. To give yourself a little youthful touch, Karen Phillips recommends wearing simple cuff bracelets, slim hoop earrings, a river bracelet or a thin necklace.

You are a fashion slave

Trends come and go, so if everything you buy follows fashion, sooner or later you'll find yourself with a wardrobe full of clothes and shoes that will make you look like they're from another era. Of course, that doesn't mean you shouldn't buy anything that is trendy, says Karen Phillips. But with all these trends, I would still ask myself a few questions before investing: will this article make me happy? How many times a week will I wear this thing? "

You seem to be in mourning

Black is chic, it slims, it gives a sophisticated silhouette. But it is also austere, a qualifier from which it would be better to dissociate oneself when looking for the fountain of youth. If you're not ready to sacrifice black, at least try adding a splash of color with jewelry or accessories to create a dapper and younger look. Karen Phillips recommends pink or coral tones because they add radiance to all skin tones.

Your heels are not high enough

"The more casual your shoes, the older you will look, whatever you wear!" claims Brittany Allen, an Austin fashion designer who worked for Betsey Johnson. If you still wear flat or cropped heels, switch them up to point-toe pumps, which will instantly add a little sexy touch to your favorite evening outfit and make you look more elegant without making you look like a matron. Are you not the high heels type? Then go with pointy flats or ballet flats.

You abuse flower patterns

With flowers, “it works or it breaks,” says Brittany Allen, especially if the patterns are faint or dull. Instead, try geometric patterns and stripes in bright colors to give yourself a more cheerful look.

You buy your glasses at the pharmacy

The right pair of glasses is the ultimate item, so don't be afraid to give it a try. Look for cat-eye frames, which are generally flattering and will instantly make you look younger. And no need to break the bank: some wholesalers offer eyeglasses at knockdown prices.
