A lot of what fans love about the AC series is the ability to transport them to a different time and culture – did you blend modern costuming techniques with what someone in Spain at that time might have used to make their clothes?

"We hand made everything for the period world in a traditional manner with modern tailoring techniques and fabrics to help achieve our own unique version."

How do you maintain the look of historical authenticity while keeping the actors comfortable and mobile?

"We built all the costumes with movement in mind. The different elements of each costume are built with hidden stretch. The sleeves of the costumes are separated from the body within the design so this cannot be seen.

Underneath the trousers are built so no kicks or big jumps are impeded. There was no compromise on historical authenticity as you cannot see the hidden parts."

Especially for an Assassin's Creed movie, the characters need to do a lot of parkour and fighting – was keep the actors ability to be that mobile a challenge for you?

"The biggest challenge for parkour movement is the boots. We made all the boots for our stunt men with parkour inner soles and ankle supports.

The outer uppers were made of soft leather so they had complete free movement and cushioning, plus there was no compromise needed for the look as actors and stunt men worn the same type of boot."

What fabric weight did you end up going with for Maria and Aguilar?

"Maria and Aguilar's costumes are mainly made from raw woven silks, over dyed and decorated by hand with beading and embroidery.

The bases of the costumes are linen and canvas to give weight and body, plus the hemlines are weighted for movement with tiny curtain weights."

Did the designs change much from your first iteration to the ones seen in the films ?

"No, the designs are basically as I drew them, the details are more defined though. As they go through the making process, the embroidery and beading became more definite and minor lines will change, but on the whole the costumes are as I designed them to be."

You can learn a lot about a character from the detail put into their clothing– is there one detail in the costume that you are particularly proud of ?

"The beading detail on Aguilar's I am particularly proud of. I wanted the decoration to look and behave like armour plating but have a beauty and fineness. This is also something Justin [Kurzel] was really interested in, instead of creating protection like is known.

It was made of small metal plates about 1.5 CM by 1 CM in rows based with embroidery silks on red suede strips.These were placed between rows of carved camel bone beads onto brown leather.

Interspersed between are tiny coral beads on the outer edges are more Y shaped beads and applique and embroidery.The whole effect was meant to be Moorish and 15th century in its origin and have a nomadic quality of fine hand work.

To be honest, Maria's I am equally proud of, for the same reasons. Hers incorporates gold metals triangles, woven plated silk stripes, wooden beads with tiger' s eye stones and small petrol blue green feathers.

This was to represent her worldliness and nomadic life style and give a tribal African feel to her body.We had a most amazing embroidery team who experimented with all the elements I gave them."

Is there an important detail that some viewers might miss ?

"All the Assassin's hoods have the Assassin logo hand embroidered at the peak. They take different forms for each character. Each is created with different threads, silks, metal beads, wires, and semiprecious stones.

Also some have the logo on various other parts of their costumes such as belt buckles, embroidery on the tunics, wrist blade buckles and other metal protective areas.This is all very covertly done."
