product information:
q: why organic materials? does it really matter?
a: we think so! first, cotton is a natural fiber and therefor biodegradable. organic cotton comes from plants that are not treated with pesticides, insecticides, herbicides or GMOs. fashion is the third most polluting industry in the world. by using organic cotton, we lessen our impact on the environment. second, organic and natural fibers are a better investment. treat your items with care - wash in cold water and lay flat to dry - and they will only get better with time!

q: why did you leave your factory in LA? what's so great about your new partner in portugal?
a: it is my goal to deliver you the best quality products that i possibly can. i am also committed to more sustainable and ethical processes. our new factory runs on 100% renewable energy. they have an AENOR green energy certificate and their solar panels give them 100% of their energy needs. they are GOTS certified and oeko-tex class I. they provide above minimum wage and better conditions for their low-level workers. all employees get morning and afternoon breaks "on the house" and they have free transportation to and from work - including a mid-day transport that allows them to have lunch with their families if they so choose. all employees have health insurance with entrance in to the best private hospitals in their city. we want to make clothes that make us feel good AND that we can feel good about. our new partners in portugal are the cream of the crop and we are thrilled to be working with them.

q: how else are you practicing sustainability?
a: we are doing our best to make our full process as sustainable as possible. as always, it is a work in progress and i welcome any feedback or recommendations you may have. our paper tags are made out of recycled materials. we ship with compostable packaging. in general, we try to use as little packaging as possible while also delivering a beautiful product. a note about our internal plastic bags, borrowed from one of our biggest company crushes, entireworld: "the damn bags. this is the toughest nut to crack, and the part we’re still working on along with everyone else who ships stuff around the world. see, the one thing you can’t get around when you’re producing and distributing all of this product is that each individual thingy has to have its own plastic bag. it’s both to track and protect the product as it moves through all of the places it needs to go between the factory and your doorstep. those two things are actually important for sustainability as well – like, if the product is lost or ruined, what a waste, right?" 

q: what size is right for me?
a:  the short answer xs 0-2, s 4, m 6-8, l 10-12

product care

q: how do i take care of my garments?
a: our products are made of 100% organic cotton. hand wash or machine wash cold on gentle cycle. lay flat to dry. the fabric softens very nicely in the dryer (on low heat) but please be aware that due to the nature of the cotton, and even though your garment has been preshrunk, additional shrinkage is likely.
