Thank you for your feedback. I'm genuinely sorry you feel excluded.
As a small independent business, we're limited by the size ranges offered by the brands we stock, many of which currently only produce up to a UK 16 or 18. We know that's disappointing, and we consistently feed this back to our suppliers, as we'd love to see more inclusive sizing.
That said, we do have a number of styles that are more generously cut and may be suitable. For example, one of our Greek Archaic Kori maxi dresses is listed as fitting UK sizes 10–18, with a bust measurement of 117cm, which may also work for some customers who typically wear a UK 20, depending on their measurements and preferred fit.
If you'd like to email us with your bust measurement and let us know which styles you like, we'd be very happy to check the garment measurements individually and give some recommendations.
Thank you again for taking the time to share your thoughts.
