Customer photo review of Rhiannon Viscose Nylon Sheer Neckline Knit Dress in Mocha

Absolutely love this dress! The fit is incredibly flattering and comfortable, it sits beautifully and drapes really nicely. The fabric feels elegant, and the pleated detail gives it such a classy, timeless look. I especially love the rich chocolate colour and the chocolate leather belt (bought separately), which gives the dress a polished and very flattering shape. I wore it to an event and received so many compliments throughout the night. It feels stylish, sophisticated and easy to wear at the same time. Definitely one of those dresses that makes you feel confident the moment you put it on.

So pleased I bought this timeless dress. It’s a perfect fit (AU 14). I love that its knit is not too heavy so it’s perfect for spring.

August 28, 2026

A classy *forever* dress. It drapes and hangs beautifully but isn’t tight - it skims over the unwanted lumps and bumps. Pairs well with simple gold jewellery.

Stunningly beautiful dress - especially for an evening out. The details provided regarding the dress were very helpful and spot on. The listing doesn’t mention that it comes with a belt which was much appreciated. I was trying to work out what belt to style it with so this was an added bonus! It’s my first purchase from Once Was and I’m sure it won’t be my last.
