Ottavia Thermal High-Waist Leggings

The warmth
Thermal high-waist leggings, bonded not sewn
The pile is bonded to the back of the knit rather than stitched in as a second layer.
That is why they stay slim under a dress instead of looking like two pairs of trousers.
They are thick and meant for a real British winter, not a chilly office. They make winter far more comfortable.
The waist
High and wide, a clean line
The band is cut high and wide, so the line stays smooth under a long knit or a jumper dress.
High elasticity through the whole leg means nothing bags at the knee by lunchtime. They stay put all day.
They are warm enough to wear on their own on cold days. They are cosy and practical for every cold day.


The versions
Plain, embroidered, leather tab or cat
Plain for work; embroidered lettering or a small leather tab at the waist if you want a detail; a cat motif if you want something to smile at.
We size them to our UK chart: S is a UK 10 up to XXL at a UK 18.

From Maria & Denis
Thermal high-waist leggings with a lambswool-effect pile bonded inside — the warmest pair in the collection, the sort you put on in December and wonder why you spent November being cold.
Seventeen versions: black, navy, charcoal and wine in four finishes, plus leopard, in sizes S to XXL.
Why you will love it

Fabric & care

Size guide
We size this style to our own UK chart. The figures below are body measurements, so measure yourself and match the row — it is a truer guide than a garment measured flat.
| Size | UK | Bust, cm (in) | Waist, cm (in) | Hip, cm (in) |
|---|---|---|---|---|
| S | 10 | 84–87 (33–34) | 66–69 (26–27) | 92–95 (36–37) |
| M | 12 | 88–91 (35–36) | 70–73 (28–29) | 96–99 (38–39) |
| L | 14 | 92–97 (36–38) | 74–79 (29–31) | 100–105 (39–41) |
| XL | 16 | 98–103 (39–41) | 80–85 (31–33) | 106–111 (42–44) |
| XXL | 18 | 104–109 (41–43) | 86–91 (34–36) | 112–117 (44–46) |
What we can tell you: the knit is high-stretch and the waistband is generous, so the sizes cover a wide range. If you are between two, take the larger — a thermal legging that is slightly roomy is still warm, one that is tight is not comfortable.

Good under dresses
Thick enough that nothing shows through. You could wear these under a dress all winter.

Proper fleece inside
Real fleece lining, not just thicker fabric. Still soft after washing.
Very warm
Very warm. Good fit. Came three days earlier than I expected.

Warm outside
Two hours out in the cold and my legs stayed warm. Did not need anything under them.
Bit long
A bit long on me at 5ft 3. Wish they did a shorter length, otherwise great.

Fit properly
I am an 18 and they do not go see through or cut in at the waist. First pair that does not.
Cosy
Really cosy, I wear them constantly.
Long enough for me
Good length at 5ft 9, they actually reach my ankle. Took the L.

Comfy in the evenings
I put these on as soon as I get in. They do not go baggy at the knee.
Navy is very dark
In dim light the navy looks black.

Waistband stays put
Wide waistband and it does not roll down when you bend. 5ft 7, took the L.
Bought another colour
Liked the first pair so ordered another colour.
Under trousers
Thin enough to wear under work trousers and still warm.
