About this style

Soft drape and delicate lace give this Per Una slip dress an effortlessly romantic feel. It’s designed in a regular fit for comfortable wear. The v-neckline is framed with intricate lace inserts that continue across the bodice and straps for a feminine finish. The lightweight fabric falls gently through the body, creating a fluid silhouette with a softly draped, handkerchief-style hem. Per Una: stylish designs crafted with carefully considered details and feminine flourishes.

A really pretty butter colour with lace accents adding interest. True to size (14) I have a full bust but slim hips so the dress skims nicely. The only draw back ( hence 4*)is that it can easily mark. I had applied hand cream & adjusted the top of the dress to find that I had left some small streaks. However after a mad panic I found that using a damp clean flannel over the area the marks were removed.

What a fabulous dress this is and the fabric, lace and design is amazing for the price. Hangs really nice against your figure and quite flattering too. i bought the dress for my best friend for her holidays and she was delighted, had many compliments when she went out in the evening!! Would highly recommend.

The dress is very pretty. not my normal style at all as I usually hate a handkerchief hem. The non creasing is great for holidays.

Gorgeous dress

Originally posted on marksandspencer.com (UK)

Absolutely thrilled with this stunning dress, it looks far more expensive than it is especially with the pleated detail and gorgeous lace and it arrived without a crease. To me it looks more golden in colour as I’d say the description of buttermilk is more yellowish. I did try on a 12 which was too loose so ordered a 10 online which is a teeny tiny bit snug around the back but I can certainly overlook that as it’s a gorgeous dress.

Gorgeous dress

Originally posted on marksandspencer.com (UK)

I love everything about this dress except the fabric - it’s polyester not viscose which is far nicer and so it’s overpriced from that point view. But it’s elegant and floaty, the perfect length, fit and colour for me so I kept it. I chose my usual size and have already worn it twice with brown suede flats.

Gorgeous dress that looks stunning on. I decided sadly to return as the buttermilk colour didn't suit my complexion. I would buy if another colour option was available
