Better than expected
I ordered this for a last minute event and it arrived quickly and looked even better in person. The fabric feels premium and the fit was perfect straight out of the bag. Will be ordering again.

So many compliments
Wore this out to dinner and had three people ask where it was from. It photographs beautifully too. Genuinely one of my favourite purchases this year.

Great quality, size up
Really lovely piece and the material is great for the price. I would suggest sizing up if you are between sizes as it comes up slightly small. That said I am thrilled with it overall.

Looks expensive
I was a bit unsure ordering online but the quality completely won me over. It looks far more expensive than it is. I have already recommended this to three friends.

Wore it to a wedding
Bought this for a summer wedding and felt incredible in it. The cut is so flattering and the fabric moved beautifully. Got stopped multiple times throughout the day. Couldn't be happier with this purchase.
