What are the pads made of?

The bra pads are made with 100% recycled polyester or 100% Modal (reconstituedted beech tree viscose). The pad does not touch skin and due to difficulty of maintaning the weight and shape of garment - we have not found commercially viable natural alternative.
You can remove it or replace it with your own options.

Which bra would you recommend for a cup size d? Thank you in advance

Thanks for checking us out! That is a very good question. The bras can be used with different sizes but I because they are less structured, the fit is trickier as the sizes go up - at least that's what we observed in our store.
Jane's bra https://naturalclothingcompany.com/collections/organic-bra/products/organic-cotton-bra have had good reviews with larger sizes, mostly because of it's solid covered back. It keeps your back and shoulder tighter in a better position and is very comfortable. It is not padded, so it does not have as much coverage as some of the padded bra.

Another good bra with lots of support is Addy https://naturalclothingcompany.com/collections/organic-bra/products/organic-cotton-padded-bra-addy or Daily Bra https://naturalclothingcompany.com/collections/organic-bra/products/organic-cotton-padded-bra-daily.My concern is that these run bit small so you probably would be more comfortable with XL, which is out now but we will be getting a new shipment shortly. 
Send us an email if you would like to be notified when the shipment arrives.

1/29/19 - Hello, I have a question. I just went to order this "Organic Cotton Padded Bra" (Daily) for $38 in natural color and it only comes in small and large. I need medium (36B). Does it come in medium size? Thank you, JR

Thank you for asking! The bra will be available soon. We are a very small company so we do run out occasionally on stock but the basics - bras, socks etc. are re-stocked regularly.  I will be glad to send you a message when it arrives (estimated a week or so).
