Wearing baggy clothes - While there is nothing wrong with a loose summer dress, most baggy clothes will not make you look great. Opt for more tailored pieces.
Wearing old-fashioned tights - You know, like the ones pictured. You might be able to pull it off with a formal outfit, but in general they'll just make you look older.
Wearing brooches with everything - Brooches can really make a blazer or a similar piece shine. But please, don't wear them all the time with all sorts of clothes.
Taking the bohemian style to an extreme - Overdoing the hippie chic style might make you look like an old fortuneteller.
Not wearing the right bra - A poorly fitted bra not only is uncomfortable, but it can also ruin your style. Maybe it's time to get your measures right and buy a nice bra.
Wearing frameless glasses - A monocle would probably look better than cheap frameless reading glasses.
Covering up excessively - You can look great with a look like this, but don't be afraid to show some skin.
Not taking risks - You can still find lots of fun pieces you can wear that won't make you look like you're trying too hard to look young.
Not embracing your sexy self - Growing older doesn't mean losing your atractiveness. Be confident, embrace your body, and don't be afraid to be bold.
When you can see your socks - Hipster kids might be able to pull this off, but if you're older, you'll just look weird.
