Both mint green heeled sandals (or woman shoes as I like to call them) are for sale on ASOS, both retailing at £45. The patent black Mary Jane's and the patent sandals, both Dr Martens, are available on ASOS retailing at £90. Alternatively the Dr Martens will most probably be available in-store, I saw these in the Covent Garden Dr Martens shop.
I have yet to buy ASOS branded shoes so feedback on the quality would be more than welcome and appreciated. As for Dr Martens, I could not recommend them more! They are the highest quality made footwear I own and have been buying them for about 5 years now and haven't had any issues at all, which is really rare.
