About Renata Grilo

Fashion designer, textile engineer, and personal stylist, Renata Grilo, was born and raised in São Paulo, Brazil and currently resides in the Philadelphia area.

From a young age, Grilo had the privilege of being surrounded by a diverse cultural bloom of colors, textures, nature and architecture. This was the genesis of Rethinktex.


At the tender age of 13, she accepted her first job working in one of the largest cotton and denim mills in the world, Tavex. There she observed great minds leading sustainability and textile innovations like never seen before. That was the beginning of her career as a Textile Engineer.


Renata graduated from Faculdade Belas Artes de São Paulo University with a Bachelor Degree in Textile Engineering and Fashion Design.


Her fashion aesthetic has always captured the attention of designers and buyers from top retailers around the world. It is a storytelling of consumer needs, beauty, and elaboration of a craft that mixes different yarns, fibers, printing, dyes, washes, shapes and fit. 


With over 16 years in the industry and having worked with the world’s most prestigious brands and designers, Grilo founded, Rethinktex, a consultancy destined to become a resource to retail brands, mills, and wholesalers for activewear, haute couture, ready-to-wear (RTW), and FR & PPE. After one year of consultancy, Renata started working for chemical companies, medical, hospitality and luxury retailers to lead and mentor in diverse roles from Operations, to team management.

When not working as a textile engineer, fashion design or the retail industry, Renata is also a personal stylist, and mentor in these areas.


Rethinktex's focus is on the client who is willing to look and experience art and fashion beyond the obvious. Rethinktex represents the coexistence of exclusive fabric, yarns, trims, colors and finished garments with unparalleled insight on textile R&D, fashion design, personal styling, consumer behavior, financial advisory and sourcing strategies. Whether you are a start up company in Fashion, Retail or Home-goods in need of some initiative planning or a large scale corporate, Renata will be extremely eager to complete and deliver the task with excellence!


Located in Philadelphia, PA, Renata Grilo has worked as a trusted fashion designer and textile engineer to many of the world’s top haute couture brands and has plans to introduce her own brand in 2023. She also has a penchant for playing the guitar, swimming, surfing, helping her community through church, spending time with her family, fluffy friend Snoopy the Maltese and appreciating architecture.


This is her story.....yet to be completed and yet to be weaved.
