The major problem faced by the clothing brands of these days is sustainability issue. The waste generated by the clothing manufacture company is causing a great proportion of solid waste in the urban areas. The cloths after few times wearing are becoming out of fashion these days (Baden-Fuller and Mangemati, 2013, pp. 418 - 427). Moreover, the rate of recycling of the fabric material is lesser than the production of these cloths. For sustainability demands, the quality of fabric cannot be compromised because it will reduce the company trust and lower the sales. Many international organizations are also boycotting the brands which are not adapting sustainable strategies for the manufacture of fabric. Many bloggers and influencers are demanding the sustainable fabric. The less buying of cloths is more encouraged these days. The same problem is faced by EthicStar Ltd (Baden-Fuller and Mangemati, 2013, pp. 418 - 427). 
The digitalization is a major problem faced by both big and small clothing companies. Innovation in the fabric manufacture mechanism to the digital market, everything is now connected with the AI. For small business like EthicStar, there is a great room to grow by the help of technology for small business the resources are not sufficient. This hinderance while overcoming, might lead the company to compromise on the quality or other aspects in order to use sufficient resources for the digitalization (Caro and Martínez-de-Albéniz, 2015, pp. 237 - 264). 

The solution for the technical lag between small business like EthicStar and bog clothing business can be overcome by taking some small but effective steps. These steps could involve the hiring of IT professionals that are willing to work for low salary but are interested to go an extra mile. The second machines for the fabric manufacture can also be bought which will be less expensive than new one.

The cost structure is utilized to define the cash inflows and outflows of a company. The out flow includes the rents, tailor prices, researches, technical advantagements, service cost of the machines, employee insurance and daily office cost. The other hand, the main inflows that a company has are the direct goods prices, funds by the government etc. The cost structure and plan for EthicStar is not unique from the other famous big clothing stores. The change is in the policies and the leniencies provided by the government of UK for SME that includes, lower taxes, lower electricity per unit price and many more (Jin, et.al, pp. 193 - 211). These costs are more or less same for the online purchases, retail stores and the exports to other cities of UK.  The cost structure is defined as the relative proportions of the variable and the fixed costs which a business incurs (Bedford, et al., 2011). The concept is expressed in the smaller units like the service, customer, product, division, or the location. 
The structure of the cost is below described :

Raw Fabric and other raw material = 60% to 70%;
Staff salaries = 10 % to 15%
Governamental Taxes and the electicity bill - 15 % to 20%

These costs are more or less the same for the online puchases ,retail stores and the exports to other cities of UK.

Ethic Star incurs the heavy range of the cost for obtaining the material and fabric for making the clothes for its clients. So in this regard, Ethic Star also has to pay high rates to the designers and the team of the logistics for their work. Lastly, it incurs the little and manageable price on the advertising of the brand.

Revenue Stream is usually termed as the monitory costs that does not include profit. This revenue is obtained directly from the customer segment (Fassin, et.al, 2011, pp. 425 - 453). This revenue can also include the one time pay from the buyer or the repeating revenues. The funds or discounts given by the authorities or the bigger companies also counts as the revenue streams. 

The pricing technique of Ethic Star is market oriented so the cost is adjusted for keeping in mind the markets such as the prices are high in the global market due to the longer distribution channels, however they are low in the terms of the domestic markets.
Various mechanisms and  procedures are adopted by Ethic Star for the revenue streams including fixed list costs,discounts and cupon codes.
