What you are designing is a lash box, here are a few ideas I like:
1. An Ombre design
2. A design that includes modern geometric shapes
3. The box has a window that you can see the lash, have the design look like there are beams of light shooting from the window onto the design
4. I like gold on gold, black on black etc. I like a box with texture ( hot stamping or uv stamping) and/or a difference in finish such as matte and glossy.
5. I love a modern chic design
Another thing that is important to know is the box template has a rectangluar window that the lash will show through. This can be customized. I will attach some options to give you an idea.
The ones I like are: H05, NL07, P808, 944
As for fonts I open to what you think will look great with the logo I already have.
I have attached a brand inspo collage. Here are a few brands that I am very inspired by their visual marketing, packaing, and advertisement.
1. Pat McGrath Labs
2. Charlotte Tilbury
3. Christian Loubittion
4. Erika Jayne ( not a company but she reflects my style)
Finally this is Encore! Its a high end lash company that is young and modern and i would like the Brand to reflect a theatrical/ hollywood glamourous vibe. Rodeo drive meets Broadway
