Hi ,A bride came into my boutique a month ago looking for lace long sleeve wedding dress. I didn't have much in a long sleeve there are a couple of dresses I can buy extra fabric and attach a sleeve to . 
I said to my bride " try this Lusan Mandongus lace dress I know his has made it in a long sleeve with the Sabrina neckline you are looking for".My bride love the lace and with my help explaining how it would look like with a different neckline and sleeves, she and ordered the dress . I was grateful that she believed in my knowledge and also helps that her mum is a seamstress that could understand what I was explaining. 
When I was in Milan I saw her dress and was so excited I asked the model to try it on. I emailed my bride the photos and she's just loved her dress even more . 
When I did made to measure a bride never got to see her dress till it was almost finished. I find ready to wear easier as they can see the dress on them and I can explain the changes to the dress.
