Prediction: This £13 H&M Top Is Going to Cause Mass Hysteria

There are high-street buys and there are high-street buys. We specialise in the latter here at Who What Wear, and as the new season approaches, our favourite affordable stores have already just received (or are about to receive) their first batch of autumn/winter 2017 goods. The first drop is usually the best drop. It's the one where runaway successes are made in a blink of an eye, and you rue the day you didn't buy that pink M&S coat when you had the chance.

There's a great deal to sift through (and it's not all pretty), but that's where our team and know-how comes into play. We do the trawling and editing so you can just sit back, click a mouse and look fantastic before the cold weather even kicks in. From the new collaboration hitting John Lewis (you are going to pee your pants when you hear which designer has signed up—I almost did) to the Mango pieces that are already out of stock and due to be refilled any day now, plus one key bargain H&M buy that shouldn't be missed, these are the most impressive high-street pieces for autumn, and we've lined them up into one easy-to-shop list.

Stop reading, start looking: Here are the best high-street items to buy this season.

Expect to see this everywhere on H&M.

If Kim Kardashian West shopped at & Other Stories…

This is just one great collab that forms part of Next's new offshoot, Label/Mix.

Following the success of that constellation-print dress, I predict this won't stay around for long.

Boden Icons is pricier than the main line, but you can see why with that intricate embroidery. The longer-line version of this coat is already selling out, and this one isn't far behind.

Warehouse's dresses are becoming something of a high-street legend. 

Whistles were the original high-street brand nailing the pleated party skirt—so the brand's new iterations never fail to please shoppers.

This jacket and the matching skirt have sold out (and you can sign up for when it comes back). In the meantime, shop our edit of other checked suits.

Our ASOS sources tell us this coat (which also comes in black) is selling like crazy.

Don't panic if this has sold out in your size; there will be more of this gorgeous frock coming.

Launching on 21 September, this gorgeous semiprecious range is a real move into high-fashion territory for the brand, and we'll be picking up these earrings.

Almost no words. These are now finally available, and judging by Topshop's previous success with a pair of silver boots, we expect these to make a splash.

This is the coolest collab to happen for some time. Eudon Choi's perfectly tailored capsule collection hit John Lewis earlier in September and this exemplary piece is almost all but sold out, bar a few sizes. 

FC's denim collection is looking really good right now, but we hear this autumnal dress is also flying off the shelves.

This incredible high-street shirt has Olivia Palermo's seal of approval.

Do we even need to talk you into this? COS's cool circular bag is already a must-have item in-store.

There are only a few of these beauties left. Move fast. 

We couldn't believe this was high street, but it is. And it's coming to a River Island store near you (or online) sometime this month. Sorry that you have to wait for such greatness…

This ultra-popular bag is back in new colourways and is bound to sell out just as quickly the second time around.

These cord trousers will be the hippest go-to for anyone who thinks of themselves as a minimalist. Until they arrive on 21 September, know that there's plenty of other corduroy must-haves in Urban Outfitters to satisfy your needs.

These come in a host of colours (and different heel heights), but we predict the pink satin is going to soar thanks to how unique they are.

So many incredible embroidered pieces in Zara's outerwear department right now, but this is the one that's really going to stand out from the crowd.

Lovely by name, lovely by nature—these are Aldo's best boots for autumn.

From our office to the Instagram world, this dress has been spotted many times lately—and the impressive sales figures match up to that.
