Hello LightLilly01, if you order it now, we are afraid it is unable to reach you before 28th Aug.
*If you order the shoes now (about 2-3 days making shoes time) and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you around 3-4 weeks after order's confirmed. n_n
*All shipping information (including methods, cost & estimated delivered date) will be shown in order page, before payment; you can pay extra cost to upgrade shipping method there.
