I can't be the only one who's noticed just how good Hailey Bieber's style has been these last few months. From straight-off-the-runway pieces from Saint Laurent to trend-focused looks for nothing more than a day of errands, her unmatched taste is absolutely showing. But super-buzzy outfits aren't all the supermodel is donning these days. She could also teach a master class in easy everyday styling, with her latest look being at the top of the syllabus.

In a series of low-key selfies posted on Sunday, Bieber showcased the ultimate timeless combo: a vintage leather jacket, a comfy sweater-vest, and a pair of blue jeans.

To slightly trend it up, she added a pair of semi-sporty sunglasses from Balenciaga and her usual body chain, but for the most part, her sweater-jacket-jeans combo will stand the test of time. It's for that reason that I immediately began searching for ways to re-create it upon spotting all three segments of her look. (I do, indeed, get notifications when she posts on Instagram.)

Ahead are all the items I found during my quest for the perfect sweater-vest, leather jacket, and 24/7 pair of jeans. If there's one thing I know for certain, it's that a denim combo as good as this one will never go out of style, especially if we keep getting sightings like this one.

Don't be fooled by the number of sizes in stock. This jacket will not last at this price.

This is what's called a worthy splurge.

I've been eyeing this motorcycle jacket for weeks.

I think it's time to go for it.

You're not going to find a jacket this good at this price anywhere else.

If you don't buy this jacket, I will.

These are the kind of jeans you'll own forever.

There's a reason why every editor has a pair of these.

Everyone needs at least one pair of ripped-up jeans.

You really can't go wrong with a pair of 501s.

These are, indeed, sublime.

I popped into COS this weekend and was truly shocked at how many things I wanted—this knit vest included.

I swear I thought this vest was at least $100.

The collar makes the vest.

Get the most out of your purchase with this multi-way vest that, even in its most basic form, is a must-buy.

Really good cashmere is hard to beat.
