Reformation Rosmarie Dress Size 12

Black long-sleeved maxi dress with a mock neckline, open back, and detachable fur cuffs.

Honey Knit Dress

Summer Wedding

The wedding guest dress of the summer. I’ll be wearing it to my best friend’s wedding in Barcelona in September. The Jillian Silk Dress in ‘pear’ is a maxi dress with an adjustable halter-style neckline, contrast paneling at the waist, and an open back. True to size and stunning for a summer or winter wedding guest.

Maven Dress in Corinne

Black-Tie

The Jillian Silk Dress is a maxi dress with an adjustable halter-style neckline, contrast paneling at the waist, and an open back. In case of keeping up appearances. 

She is a gorgeous pear/olive colour with darker green features and so stunning 🤩 

This dress is a US10 but I am a UK 12 and would argue this is best suited to a 12 for the perfect fit.
