Here is the finished look:
First you will need a chunky sweater. This particular sweater (cowl neck & cable knit) I got at Akira Chicago.
To give the sweater a more fitted looked I decided to take a gold belt and cinch my waist with it. This will not only give my body more shape (curves), it will also draw attention to the smallest part of my waist.
Another important thing to do is roll up your sleeves! It will make the sweater look more fitted to your body and less baggy.
Now some finishing touches to the outfit. Adding a lace slip or dress underneath will make the outfit softer and more feminine (I got the lace dress from Dry Goods). Pairing this up with a pair of suspender tights will give your outfit a more alluring and sexy vibe (Black Bow Suspender Tights are from ASOS).
