Obviously, dossier is helpful, to begin with. There you can see the story of each collection. I've spent several days putting together the collection. To make matters easy for me, I've always chose top store where garments of the season is almost complete. Else, there would be proposal of transfers.
But before the actual show, there would be fittings of models. Set cards of models are sent to me beforehand for their stats: measurements, size of shoes among others. Good thing that the store team always be on hand to assist me anytime. This is not a one-man-show, after all!
I always chose weekdays so there would be not much 'traffic' in the store. This way, fittings would be somewhat a 'breeze'. Models would be given specific (fitting) time from their agency, so as not to come in full force. And for me too to allot ample time for each model during fittings as there would be newer selection and changes in the process. Tedious actually but in control just the same. And not to mention male models who took my breath away. Charot! Kind of hard to consistently acting like a pro when in fact you are dying inside. Hoi! LOL.
