100% Cotton

Perfect for special summer occasions, our Merthen Dress is made from beautifully textured cotton. It falls below the knee and has a classically feminine shape with a gently fitted top and defined waist, falling into a softly pleated full skirt. It has a scoop neck, decorative button placket at the back and side zip fastening. We think it looks great with wedges or elegant leather flats. Also available in Petite and Tall.

Another Seasalt Cracker!

Another of your exceptionally beautiful dresses which I love. In particular, apart from the stand out colours, thank you for the minimal exposure round neck which is great and flattering and means I can wear earrings without bothering with a necklace.

Beautiful dress

This dress is perfect for me. I am a 12/14 and the 12 fitted so I would suggest that the sizes are large. The material is an unusual weave but is cotton so right for warm weather (if we ever have any). I am 5 foot 8 and chose the 'tall' which comes a few inches below the knee. The skirt is quite full so I prefer a longer length.

Beautiful quality dress

This is a lovely dress, beautiful quality fabric and lovely print. I ordered the tall fit which was perfect for my height 5’10” but unfortunately the style just didn’t suit me. I made my hips look too wide.

Lovely summer dress

I thought I deserved a new summery dress this year. I was a bit unsure about the colours when I ordered the dress, but they’re lovely in real life. The fabric is great and overall, the dress looks really nice.
I do have one quibble about the fit though - it gapes at the neckline - I can’t quite work out why, but there’s something odd in the design. It’s not terrible, but rather irritating for quite a pricey item.
I’m keeping it regardless, but might have to put a couple of small darts in.

Schönes Kleid

Das Kleid passt genau und fällt wunderbar. Die Farbe entspricht der Abbildung und ist einzigartig. Ich trage Größe 40 und die englische Größe 14 ist genau richtig. Da ich lange Beine habe, ist tall die richtige Länge. Ich kann das Kleid sehr empfehlen!

Lovely dress. Beautiful material and lovely quality. Really love this dress but it was too tight on the bust so had to return it. Shame you don't do it in bigger sizes. I would need to get it altered but it would be worth it. Really sad!!!

Merthen dress

I so love the colours in this dress. I had to have it straight away. Unfortunately for me, my shape does not work well with fit & flare. I have a large waist. I am also smaller on the top & bigger down below. So I bought a size 20 for the bottom half & luckily in our high street we have an alterations shop. when shops have opened again I shall have the top reduced down. I may save this dress for my friends daughters wedding in June.

Lovely happy colours and fabric. Could be dressed up or down
I'm quite busty and only 5ft tall. I don't like too tighter fit so ordered the size 18 in a petite and the fit was perfect.
I love the dress - roll on summer
Thank you Seasalt for my nhs discount. I've never afforded clothes from you before and you have cheered me up no end.
Well Done on the paper packaging too.
I hope your shops survive this pandemic- we need you.
