Ok I have been seeing a ton of collarless jackets and I love it!!! I see collarless jackets and see chic!!! One of these jackets can turn several outfits into a fit-for-work look. My favorite thing about not having a collar is that it wont hide a super cute neckline underneath.
Just think about your coat that you have and its traditional collar and if you wanted to wear a dress with a collar and big bow on the neckline. Now think of that same outfit with a super cute collarless jacket ala Chanel.... now that is a perfect example of why this is a perfect jacket.
You can always mirror the frame that the neckline provides with a collarless rounded dress or blouse.
Tip: If you want to be chic and glamorous wear a collarless jacket with a sheath dress to brunch. Nothing is classier than those three things... Just ask Chanel.
Most collarless jackets have a rounded neck and are a more square shape. If you already have a boyish figure then you should go for a more tailored jacket that either ends at the natural waist or has some curve in the side seam. If you have a bigger backside then don't do a cropped jacket... it will draw attention to your butt.
The best part of most collarless jackets is the trim on the edge to give a finished look. I have seen chains, lace, beads, rope and so many other trim on the edge. Also because this jacket is a more casual alternative to a traditional suit jacket it is able to be worn more often and anywhere.
Make sure and go out to get your stylish collarless jacket before it saturates the market and becomes out of style.
