Staple with a twist. Goes with everything.

Love it, have worn it loads. It's very wide. It not too short. I think overpriced for what it is but I enjoy wearing it a d I wanted a lightweight loose style sweatshirt. Oh and I got ID'd in Waitrose when wearing making me look youthful too! 😂

Lovely fit and quality. More boxy than previous sweatshirts from whistles

Beautiful fabric and fit. Loved the boxy style. Put it on straight away.

Excellent style, bit quirky and fun. Not yet washed, and I chose S. I’m mindful that Whistles items do often shrink even when washed on 20.

Love this sweater, it’s oversized in the best way. It’s nice and light for this time of year too!

I had such high hopes for this jumper as it looks so nice on the model but it’s so shapeless and short in the body (I bought a small) so has gone back.
