Get top marks with a blazer this season, says Georgina Heffernan.

Q. I want to invest in a new jacket for autumn but I’m not quite sure what style to go for. Any suggestions?

A. Fashion chain New Look recently announced that a "huge" fashion trend for the coming months comes in the form of the blazer. As far as women's jackets go, they’ve earmarked it as the sexiest style so far. According to a release, the piece, which has been on the radar since the end of summer, will form the linchpin of most autumn wardrobes, as it’s a great transitional garment that is effortlessly chic.

So, if you invest in just one thing this season, make sure it's a LBB (that's a little black or blue blazer). It's perfect for throwing on over a dress or the no-brainer blazer and jeans combo instantly shows style with a relaxed vibe. Somewhere in-between grown-up smart and trend-savvy, the blazer has assumed many forms, colours and styles this season, whilst staying true to what it does best: dressing up an outfit with instant cool.

From the romantic velvet blazer that recalls sixties boho-chic, to the tailored pleated jacket that has a couture feel and will boost any outfit for a formal occasion. In between the two you'll find ladies blazers in chord and lace to fit all tastes. The beauty of the blazer, perhaps, is that it works with almost everything...

How to wear the blazer
The blazer is probably one of the easier items of clothing to wear. If you don't like playing dress up in an overly glamorous way, throwing a sequinned or sharply tailored blazer will transform a pair of jeans into red carpet ensemble. Boyfriend blazers have made an appearance and look equally effective for a cutting edge, on-trend relaxed look. Be inspired by New York bands, supermodel slouching, tailored sophistication, and treat yourself to a blazer. Here are some great styling ideas.
