Sienna's Slouched Double-Buckle Block-Heel Vegan Leather Knee-High Boots are your go-to choice for effortlessly polished autumn and winter outfits. Crafted with a softly draped, slouched shaft, two decorative buckle straps and a sturdy block heel, these knee-high boots are perfect for women who want a put-together look without any extra effort.

Why You'll Love It

  • Double Buckle Straps: Two decorative straps with polished metal hardware, one at the ankle and one at the calf, add a structured, confident edge to the silhouette.
  • Slouched Knee-High Shaft: The gathered upper drapes naturally against the leg for a relaxed yet elegant finish that skims the knee.
  • Comfortable Block Heel: A stacked, stable block heel gives a flattering lift while keeping you steady on your feet all day.

Perfect For

Pairing with straight-leg jeans and a chunky jumper for a relaxed weekend look, wearing with a midi skirt and coat for a polished autumn outfit, styling with tights and a dress for a smart evening dinner, or layering under a longline jacket for an effortless city day out.

Care Instructions

  • Wipe clean with a soft, damp cloth to remove dirt and dust.
  • Avoid prolonged exposure to direct heat or sunlight, which can cause the upper to crack.
  • Use a shoe tree or stuff the shaft with paper to help the boots hold their shape when not worn.
  • Store upright in a cool, dry place away from moisture.

Really pleased with the quality

Ordered a cardigan and blouse together and I'm very pleased with both. The cardigan has a nice weight to it and the blouse fits as expected. Everything arrived neatly packed after about a week.

Much better than expected

Bought two polos for work and they've quickly become favourites. The material feels good, the collars keep their shape after washing and the sizing was accurate. I'll probably order another colour.

Helpful customer service

I put the wrong postcode in by mistake and emailed straight away. They replied the same day and corrected it before dispatch. The jacket arrived a week later and fits beautifully.

Good overall experience

Ordered two shirts. One fits perfectly and the other is a little more relaxed than expected, but still wearable. Delivery was straightforward and tracking was easy to follow. Good value overall.

Looks more expensive than it was

Wore this dress out for dinner and had two people ask where it was from. The fabric falls really nicely and the neckline is neatly finished. It also looks very true to the website photos.

Found exactly what I needed

Was looking for something smart but not too dressy and found a blouse very quickly. The site was easy to use and it arrived looking exactly like the photos. Very happy with the fit.

Simple website and a good jumper

I'm not keen on spending ages shopping online, so I liked how simple the site was. The jumper arrived in about a week, feels soft and fits well. No complaints from me.

Lovely trousers, slightly generous sizing

These hang really nicely and are very comfortable around the waist. The fabric doesn't cling and still looks smart enough for work. I'd probably size down next time, but otherwise they're lovely.

Spot-on fit straight away

Ordered a navy shirt and lightweight jacket and both fitted properly straight away. I'm just over 6ft and the sleeve length was perfect. Tracking updated normally and the quality is very good.

Good jacket for the money

Really decent casual jacket and pretty much what I wanted. The fabric feels good and the zip seems sturdy. Sleeves are a touch longer than I'd normally wear, but I'm still very pleased with it.

Lovely dress, slightly slow delivery

The dress is beautiful and the colour looks just like the photos. Fit is flattering without being too tight. Delivery took around nine days, a little longer than hoped, but I'm very happy with it.
