Jackets, if worn well, can add a lot of chic to an outfit. But the trick is in choosing the right cut and size. Here are some options:

Shrug
It’s a woman’s close-fitting ek-dum chota jacket, snipped off at the front and back, such that only the arms and shoulders get covered! A variation in this variety would be the cropped jackets with cut-away sleeves. A good bet to sport these ‘shrugs’ would be with a smart pair of jeans coupled with full-sleeved, turtleneck/boat-neck tees.

Bolero
This is once again a short woman’s jacket but it’s buttonless, and hence has an open, unfastened front.
Boleros look stunning on figure hugging, knee-length single-piece sheath dress. Also, on pastel-coloured polo-neck tees teamed with low-waist jeans or corduroys. You can effortlessly create the illusion of sexy empire-waistlines donning these boleros. It works great with party-philes, who love flocking to nocturnal eve bashes.

Jeans jacket
This is usually a jacket falling slightly below the waist, and is made of denim. It has shirt-like buttoned band-cuffs, and waistband that can be adjusted with snap-button closures. These jackets look quite awesome on bright hued (like cherry red, emerald blue, et al), high-hemmed tops paired with jeans.
Of course, instead of jeans, you can even go for denim skirts too, but don’t forget to cover your legs with knee-length boots to keep you comfy.

Spencer jacket
This is a waist-length, generally double-breasted jacket, ending just above the waist.

Hike up your chic quotient by donning these jackets on tank tops or noodle-strapped tops, along with jeans or corduroys. You can even button it over longer tops to give your dress once again that empire-waist look.
Also, you can try sporting these jackets on knee-length ‘shirt-dress’ - a collared, short/long-sleeved dress with front buttons and a fuller lower half that suits most body types.

Parka or Anorak
This is a warm wind-proof hooded jacket, which’s generally worn as protection against cold, wind, etc. They look quite cute if they are well co-coordinated with the right attire.

Select some pleasant coloured parkas like lime yellow, powder blue, etc. Wear it over short, fitting/ruffled tops, teamed with black corduroy/tights. Indulge in tomboy styling!

Bomber jacket
It’s a front zippered waist-length jacket that fits tightly around the waist and cuffs because of its elasticated bands.

This jacket is a great bet when you’re squirming to show-off your not-so-good top! Yes, you can slickly cloak the top under this cozy jacket!

In case you feel this kind of jacket looks a tad rakish, then you can temper down the effect by choosing neutral tones like beige, steel gray, even classic white.

Blouson
This is a short loose-fitting jacket that’s pinched at the waist. A good idea is to select some fluid fabrics like chiffon, etc, and to have them tailored into these jackets. Electrify your eveningwear by clubbing these blousons with sleeveless floor-length skirts, or asymmetrical hem-lined skirts.

Blazer
This is a jacket displaying colours/badge of a club, sports team, etc, and which’s generally not worn with perfectly matching trousers/skirts.

Well, if you’re a member of some elite club/organisation, make a cool statement by having its logo emblazoned on your blazer.

Biker jackets
This is a leather jacket, usually black in colour and mostly worn by bike riders. This jacket is quite an impeccable choice for winter evenings, especially if you’re a regular long distance commuter. You can club these jackets with some alluring tees and washed jeans, along with keds/sneakers to protect your feet.

Just pin back your hair with a sassy bandanna, and enjoy the wind whipping up your face as you zoom around the city in your vehicle! 

Trench-coat jacket
This is a multi-pocketed jacket falling till the knees, with a centre-fastening belt. If you’re the one for whom comfort is the top priority, and who gives a toss to accentuating your assets, well, this jacket is exclusively for you.

Remember, one positive attribute of this jacket is that you can hide those unsightly saddlebags and love handles, if you have any! Besides, you can hide most part of your dress too.

Finally, in case you’re looking at formal wear jackets, there are always those suit-coats and tuxedo-styled jackets.

Wrap up your body snugly, but remember to expose your sense of style!
