Welcome to Leigh's List . A weekly column, a bit like an agony aunt, but for your shopping woes. A self-confessed shopping addict, Leigh Campbell enjoys nothing more than hunting down the *thing* you've been searching for but haven't been able to find.

Isabelle asked:

Okay, I'm cold. It's officially chilly where I live and I have quite a few winter knits I love, but I'm not quite sure what to wear over them.

I know you love trench coats, so I would love to see some of your favourites, but can you also share some good coats and other layers to wear on top of jumpers for commuting and when outside in the cooler weather?

Watch: Comfy lux hacks for really long days. Post continues after video.

Leigh answered:

Ah yes, outwear.

As an Aussie, depending on where you live, you might be able to get through winter with just knits, or even a long sleeve top if you're up north. But those in the southern parts of Australia know the need for good outerwear.

Most indoor places are well air-conditioned these days, but the bus or train ride, or weekend kid's sport on the sidelines can definitely call for warmer layers on top of your jumper.

Here are my favourite outwear catalogues and my top picks for this season.

The classic coat.

A classic coat will last you decades and take you from the office to the footy. Warm, structured, chic. A good one in your closet will revolutionise your wardrobe.

Try these:

Piper Oversized Double-Breasted Coat , $249.95.

Basque Shawl Collar Wrap Coat , $199.95.

Sussan Draped Coat , $149.95.

Preview Tailored Coat , $100.

The trench coat.

A bit like a coat but more lightweight, I love a trench in Sydney because I feel like the weather is transitional more often than it is really cold. They can be styled to be sporty-cool, or paired with more classic outfits.

Try these:

Mossman Brown Trench Coat , $309.95.

PULL&BEAR Basic Trench Coat , $109.

The Fated Aliah Trench , $149.95.

Ena Pelly Carrie Trench Coat , $299.95.

Marks & Spencer Pure Cotton Stormwear™ Longline Trench Coat , $165.

The coatigan.

Comfort is king with this style. It's a cardigan, but it's longer and wraps around a button or tie waist to secure. Yes, there's a danger you might look like you're wearing a bathrobe, but who cares when you're so cosy and warm (steer away from white and leave it open if you want to avoid that look).

Try these:

Forever New Mariah Longline Coatigan , $169.99.

Forcast Eileen Longline Coatigan , $99.99.

Kmart Trench Look Coatigan , $40.

Sportscraft Cotton Cashmere Coatigan , $249.99.

Super Soft Lounge Hooded Coatigan , $80.

The denim jacket.

Not the warmest option, but super versatile. I love an oversized denim jacket on top of a jumper, or even a t-shirt if the weather decides to play nice. And don't be scared to do double denim, as long as it's not the exact same fabric it totally works.

Try these:

Seed Heritage Relaxed Denim Jacket , $79.95.

Cotton On Oversized Denim Jacket , $69.99.
