Hi EMF !!
Think roughly it will take 2-3 months ? Mine is a relatively simple gown and only need embroidery and beadings...I sign up in Nov, finalize design and did my measurement in Dec, first fitting early mar, i had a 2nd measurement 2 weeks after that and final fitting end of march...=)
Depending on the design of ur gown then need to prepare the heels rather early. For my case, i need to get it even for my measurement taking =)
guess it's best that u check with amanda on this
