Did you know that the average Australian woman is 5 foot 4? Globally, it's closer to 5 foot 3.

I came across this information recently while researching a story about petite fashion. And yet, as a woman who is literally average height, it is almost impossible to find a pair of jeans that fit.

To use the internet parlance, make it make sense.

Watch: The Uniqlo pants we can't stop talking about. Post continues below.

I understand that lots of women are tall or long-legged, but it's clear many of us do not sit in that camp. So why are standard denim lengths so… lengthy?

I asked this question while trying on jeans in General Pants once. The shop assistant told me a representative from a popular denim brand said it's because you can have your jeans hemmed, but you can't add length.

So, many of us are left cuffing, folding them under or having them altered, which affects the integrity of the hem seam.

I've done all of these things, but my Holy Grail would one day be finding a pair that works for my legs, waist and bum without requiring any nips or tucks.

Don't think I haven't tried. My collection is robust: I've currently whittled it down to styles I like from ABrand, Wrangler, Levi's, Feather + Noise, Ceres Life and Cotton On — but in the back of my wardrobe is a sad denim graveyard; a money pit I seem content to keep digging away at.

Case in point: a few weeks back I went to Melbourne for a solo weekend away. I had a few things on my shopping wishlist, but at the top was a pair of straight-leg blue jeans. Not barrel, not baggy, no bells and whistles.

I started the journey on the denim floor of David Jones on Bourke Street. They've got a great range including Agolde, Neuw and Nobody. I almost left with another pair of Levi's, but the fit wasn't quite right.

My friend convinced me to go into COS, which is a store I don't visit often. The tailoring doesn't really speak to me — but pardon moi, I was unfamiliar with their denim game.

I came across the Arch Tapered Jeans and they looked good on the hanger; mid-blue wash, streamlined fit, with a high waist and cropped ankle.

When I tried them on I just knew straight away: they were coming home with me. At $159, they were in the budget too.

My friend and I were heading straight to dinner and I changed into the jeans in a public bathroom — as she said, that's how you know you really love something. You can't wait to put it on your body.

I've shared a whole post about this, my "would I wear it tomorrow" theory, but I've never been so keen I've basically worn an item out of the shop.

When I posted the jeans on my IG feed, they seemed to scratch an itch for lots of my followers too. I had an unprecedented amount of dm's requesting the style name and details. When I shared the link, the clicks were insane.

Why? Because we're all looking for the Holy Grail Jean. We've been searching for years, decades.

Styles change and evolve with trends, but the lure of a perfect blue straight-leg remains. I really believe it's as close to timeless as a piece of clothing can get, and that's probably because it echoes the original Levi's prototype which harks back to the 1870s.

Arguably, this is why the 501s have remained so sticky in the public consciousness, and so popular at a retail level. They were cool when Princess Diana wore them in the '80s, they're cool when Hailey Bieber wears them now.

The thing is, images of Diana or CBK in their perfect denim might be on the forever moodboard, but a lot of us are left wanting for well-fitting jeans.

The response to the COS pair just proves my theory that there aren't enough designers — denim or otherwise — catering to the average woman.

My new jeans aren't perfect. They're snug around my bum and slightly gapey on my waist after a few wears, though I love the length. Love the fact I don't have to cuff the hem and pretend it's a styling thing. I'll take the win for now.

But the truth is, I'm still searching.
