Hello Larisa, the time is a bit tight, but should be able.
If you order it now (about 2 weeks making costume time) and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you before 6th April, but we are afraid we are unable to 100% guaranteed the exact dleivered date, hope you can understand.
*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.
*Please remember to mark down the date (you need it) in the order form when you order it, so our tailor will alert and put your order in higher priority. :)
