I found the dresses to be absolutely stunning. There is so little on the market that is actually just simple and elegant, not just simple and boring. i wanted something really vintage but modern and I have bought 'The Lola' as my wedding gown. The girls in the shop are really lovely and helpful and they helped me with my flowers and hair too. They're young and they really know the collection and are so professional, and didn't even blink when I was a bit of a bridezilla. It's so much more understandable (price/ fitting-wise) than anywhere else I went and the studio is really cute and welcoming. I'm so happy with my dress!!
The dresses at Johanna Johnson are good but not great. While some of the dresses do have nice detail, most of them are very simple everyday dresses that an average dressmaker could make at very (very) small fraction of the price.
Most of the dresses I saw were around the $4000 to $5000 mark.
