Womens Clothing size guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Collar: measure around the base of the neck where the collar sits.

Chest: measure the chest at the fullest part, placing the tape close up under the arms.

Waist: measure the natural waistline.

Inside Leg: measure from the crotch to where your trouser is normally worn on the shoe.

Jacket Length: measure from the centre back of your neck to your hemline. Then length measurement will vary depending on the style.

Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.

Bought in the sale,...

Bought in the sale, so great value for a simple layer to add extra warmth. I'm a 12-14, and bought a size 14 and was a good fit. Very long sleeves which I liked as I'm tall and it helped keep my hands warm too. Added a good extra layer of warmth during the evenings and nights under the stars at a recent festival.

Bought in the sale....

Bought in the sale. Works great at the price, lightweight but kept me warm on hikes and during a couple of days chilly climbing on sea cliffs. Great value.

I was disappointed to find that it was not 100% merino but i guess that's my fault for not checking more carefully before clicking.

Lovely warm thermal top. I haven't worn this skiing yet and I think it will do a great job keeping me warm and keeping sweat away, it's breathable and warm.

I ordered two but can't remember which one was the Alpine. So, I'd say fit for purpose.
