WHO THINKS THIS IS A GOOD IDEA?

I HAVE BEEN THINKING OF STARTING MY OWN BUSINESS SINCE THE BEGINNING OF THIS YEAR. FASHION HAS ALWAYS BEEN MY PASSION AND I TOLD MY SELF THAT I WOULD LOVE TO OPEN A STORE IN WHICH I WILL BE SELLING PROM DRESSES, EVENING DRESSES, COCKTAIL DRESSES, MOTHER OF THE BRIDE DRESSES AND PARTY DRESSES. I WAS TOLD THAT OPENING A STORE COMES WITH A LOT OF RESPONSIBILITIES AND THAT I SHOULD START VERY SMALL AND GRADUALLY WORK MY WAY UP. SO INSTEAD OF OPENING A STORE, I WANT TO HAVE A SERVICE CALLED DRESSES TO GO, IN WHICH I WILL HAVE THIS DRESSES ON MY WEBSITE AND OFFER PEOPLE THE SERVICE OF COMING TO THEIR HOUSES WITH THE DRESSES AND THEY CAN TRY THEM ON AND IF THEY LIKE IT, THEY WILL BUY AND PAY ME RIGHT THERE AND THEN. I TOLD MY SISTER ABOUT THE IDEA AND SHE SAID THAT IT IS A VERY BAD IDEA BECAUSE I WILL BE ROBBING PEOPLE OF THEIR SHOPPING EXPERIENCES. BUT I THINK IT IS A GREAT IDEA. PLEASE TELL ME WHAT YOU THINK AND ANY ADVICE WILL BE APPRECIATED. THANKS

Payment-will they pay the price or try to bargain you down?(You sound young
