What binds BJP leaders Murli Manohar Joshi, Shahnawaz Hussain, Rajiv Pratap Rudy, Congress leader Jyotiraditya Scindia, the Paswans (father Ram Vilas and son Chirag), Bajaj Group chairperson Rahul Bajaj with Lalu and family? A common thread that runs through them is the cloth they wear, designed by Champaran-born fashion designer Mohammad Azimur Rahman.

Health minister Tej Pratap will soon sport Rahman's special creations during his horse-riding sessions, a break from the western outfits he has been seen in so far.

Lalu's elder son has ordered a new wardrobe, one that exudes of Indianness, for his horse-riding trips.

"This time, I have especially designed several sets of horse-riding dresses for Tej Pratap, including Jodhpuri breeches and bandis (jackets) of four different colours. I hope to deliver them by month-end," Rahman (36) said.

Rahman has been supplying designer attires for different ceremonies and occasions in the RJD's first family for quite some time now.

Even during the swearing-in ceremony of the Grand Alliance government on November 20 last year, Lalu's younger son Tejaswi, who took oath as deputy chief minister, had adorned a kurta-pyjama and bandi especially designed by Rahman for the occasion.

Just last month, Rahman had sent the brothers their winter wear consignment of woollen garments made of fine virgin woollen yarn. "My preparation of winter wear for the deputy chief minister and his minister brother included kurta, pyjama and bandi of five different colours. All kurtas were made of fine pashmina (a kind of Kashmiri wool) and the pyjamas and bandis of high-quality yarn," Rahman said.

Rahman's celebrity client list is a long one and spreads across political parties and professions.

It includes sitting and former ministers like Murli Manohar Joshi, Sharad Yadav, Ram Vilas Paswan, Shahnawaz Hussain, Prabhunath Singh, Prem Chandra Gupta, former Bihar Governor Shafi Qureshi, Union minister Rajiv Pratap Rudy, Shivanand Tiwari, Congress leader Jyotiraditya Scindia and LJP MP Chirag Paswan, industrialists like Bajaj Group chairperson Rahul Bajaj and also some Bollywood aspirants.

Rahman belongs to Phenhara village in East Champaran. "After passing out from the National Institute of Fashion Designing & Technology, I established my own boutique, Protein, in Haus Khas, Delhi, in 2001, and gradually became popular with political leaders of different parties," he said. The Bihar connection must have played a part in taking him to the RJD chief. Lalu was the first politician he dressed up. "I first met Laluji in July 2003 when he was a Rajya Sabha member from Bihar, and offered to prepare a dress for him for his Pakistan visit in August that year," Rahman said.

"Later, I also prepared a dress for him when he presented the Railway Budget in the UPA I government led by Manmohan Singh in 2008." Lalu chose to wear a Protein kurta and pyjama that time.

"In the past few years, I came in touch with other members of his family and have designed a number of dresses for different occasions in the family, including Lalu's daughter Raj Lakshmi's wedding last year," he said.

Both Tej Pratap and Tejaswi, he said, were particular about the colours they choose to wear. "They prefer white kurtas and pyjamas and prefer bandis of sober colours," he said.

Rahman's aspirations extend across shores.

He has tried to dress the most powerful man on the planet too.

He claims to have specially designed and sent a dress for US President Barack Obama a few years back.

He had prepared a kurta of pista green colour and a white pyjama of fine muslin khadi with olive green motifs and sent it to Obama when he first became President in 2008.

There is no evidence that the US President wore the dress, but that has not dampened Rahman's spirits yet.

He wants to dress Prime Minister Narendra Modi too. "I want to make him wear a kurta, pyjama, and bandi of fine cotton yarn and prince suits from his fine woollen collection." He had designed and sent a kurta to Modi in 2012, on the 10th anniversary of the Godhra riots, to remind him of his responsibilities then as Gujarat chief minister.

Another project close to his heart is to dress former deputy Prime Minister Lal Krishna Advani in a kurta.
