What a guy MUST have: The hottest fashion trends this season!

Safari jackets, bright and cheerful sweaters and trench coats are making a comeback this season. Here's what you must consider investing in this winter.

Blackberrys, the Indian menswear brand, launched its Fall-Winter 2013 collection at a closed-door fashion show in Mumbai.

Celebrating the best of new age cinema, Blackberrys roped in movie stars Abhay Deol, Aditya Roy Kapur and Siddharth Malhotra to walk the runway.

Shruti Haasan turned up the heat on the red carpet, as did models Nina Manuel, Soni Kaur and Archana Kumar and actresses Monica Dogra and Nimrat Kaur among others (See their pictures here) 

Even so, the real stars of the evenings were the clothes featuring bow ties, tweeds, checks, sharp trousers and colorful chinos all mixed and put together in style.

So how can you look smart this winter? Sit back and take notes!

Let's start simple, shall we? The waistcoat has been a part of traditional Indian fashion for decades now and is probably one of the easiest to adapt to if you're not particularly fashion forward.

If you're still hesitating, take heart from the fact that Pandit Jawaharlal Nehru wore it over 70 years ago and to whom the jacket owes its name! So take that leap of faith and team up the Nehru Jacket with a set of western formals.

Invest in a stylish sweater this season. Not dull blacks and navy blues you wore in school. Go for something bright and colourful. You won't regret it. 

If you can, also get yourself a tie to go with it. No wardrobe can be complete without one.

The funny thing about checks is you can either get them right or get them horribly, horribly wrong. They can add inches to you that don't exist and make you look older than you really are.

Here, Student of the Year star Siddharth Malhotra models a chequered tweed jacket and a bright yellow sweater that's smart alright but makes him look more like a professor. Watch out before you pick one up, though that mustard coloured sweater could well be worth a try.

What holds true for checks also holds true for the double-breasted jacket (left). Wear it with caution. Ensure the extra pounds around your tummy are off before you try one on.

Jackets-on-sweaters can be equally tricky. The key to not looking like a stuffed penguin is to contrast the colours. If you're feeling adventurous try out a bright coloured sweater (left) or team up a more demure shade with a lighter coloured jacket.

What can we say about the classic three-piece suit that hasn't been said already? If you really love suits, it is most likely that you probably own one of these.

But the thing about the three-piece suit is that needn't always be in dark, depressing colours which make it look like you're heading for a court hearing or a funeral. Here, a dash of blue on the shirt and the prints on the tie bring to life the otherwise sombre grey.

The double-breasted jacket has been a regular on the runways for the last few seasons now and it wasn't entirely surprising when the trench coat came along in this collection.

Few things are perhaps as British as the trench coat that was developed as a garment for the soldiers. While there has been some debate about who invented this smart garment, we do know that it was first worn by the British officers in the trenches of World War I.

Eventually the trench coat would be immortalised by several movie stars, most memorably by Humphrey Bogart in Casablanca and would make its way into high street fashion.

While on military fashion, up next we have Aditya Roy Kapur wearing a modern interpretation of the safari jacket.

Even though, the safari suit is considered a relic of pre-Liberalised India, we haven't missed spotting it on the Indian runways -- designer Nupur Kanoi recently redesigned it as a women's garment -- and we wouldn't be surprised to see more of it amongst the menswear lines in the seasons to come.

Unless you're moving in certain circles, you possibly wouldn't want to be seen dead wearing a dinner jacket.

However, should you find yourself shopping for one, here's what you need to know: a variation of the traditional British tailcoat, the dinner jacket evolved as an 'informal' option for, well, dinners at home that didn't necessarily involve guests.

Over the decades though, the dinner jacket has come to be accepted as a more formal outfit as tailcoats pretty much went out of fashion (except at royal British weddings).

Admittedly, bow ties (especially coloured ones) are ones for evolved fashion souls. If you can't get around to wearing a Nehru jacket, we suggest you give this one a pass entirely.

From being a highly formal piece of garment, the bow tie in its latest avatar can be surprisingly casual, fun and is probably available at a funky street-side store in your city. So if you do see yourself in something that's pictured above, knock yourself out.

The times of 'any colour is alright as long as it's black' are gone. If you keep your eyes peeled, you'll be surprised at how many young men are taking to colour.

Walk down the most fashionable street in your city and you'll see what we mean. Even so, it does take an awful lot to slip into a pair of green or orange or a red trouser as is the case here. Then again, the world belongs to the one who dares, doesn't it? Give it a shot, we say. And see how it goes!

Aditya Roy Kapur, Abhay Deol and Siddharth Malhotra take a bow at the end of the show.
