Everytime that Fifth Harmony gets on stage during their "Reflection" tour, fans should keep Marina Toybina's name in mind.

Toybina is the creative mind behind the group's looks during performances. The costume designer, who has worked on other tours, such as Katy Perry's "Prismatic," Taylor Swift's "Red" and Ariana Grande's "Honeymoon" tour, has been working with the pop group since they first met on "The X Factor."

While talking to MTV, Toybina, who currently also designs costumes on the dance show "So You Think You Can Dance," discussed the details of her collaboration with the group.

"I have such a great relationship with them because I've known them since the very beginning, so we have very open communication," she said. "I know what they're into and what they're about, so when it came time to do the tour costumes, we collaborated. I'd have my ideas based on their individuality and who they are and what I know of them. Then I'd sketch down a few designs and send them back and forth until we were sure the fit and the style was perfect.

The Emmy-winning designer also explained how, because each member of Fifth Harmony is very different when it comes to personality and individual taste in fashion, she focuses on giving each girl a unique look. She maintains their individuality by adding embellishments, choosing to add sleeves or over-the-knee socks to a look, while still striving to maintain group unity through color.

One of Toybina's most popular designs for the group are the blue outfits they wore for the opener of the second half of their tour. According to InStyle, Toybina spent nine days designing and creating the five beaded outfits to make sure they catered to each group member.

"My main focus was to bring their image to life, and at the same time make sure that they're comfortable on stage," she told the magazine. "I'm aware of their body types and their likes and dislikes, so I just study their silhouettes and accenting their best features."
