Sure- no problem.
First, you want to make sure that your sweater is serving the purpose of a top or a jacket, not both. (i.e. You don’t want to be sweating indoors and fine outside.) Material like cashmere is a good option because it keeps you warm while inside and is also thin enough for you to wear a jacket over.
Second, the idea is always balance! So, if you have a chunky or loose fitting sweater, pair it with something more fitted. (i.e. There are some very cool patterned leggings/tights out for fall, slim pants (skinny jeans) or a pencil skirt.) These will be more of your “jacket” type look. If you’d rather go with a less structured piece underneath (a dress) then create some kind of shape by adding a belt.
As for the ‘ballerina’ or wrap style sweaters, these are usually more form fitting. The best way to wear this is with something of volume (suggestions: skirt or wide leg pants).
Hope this helps!
Get excited for fall… I am!
