I cant tell you exactly how this works (I plan to keep my name all the time) but I do have a tinge of experience here. My FIRST name is Michelle, my nickname 'Molly' grew out of.. -I'm not sure where it came from actually-but the point is'Michelle' is listed on all my legal documents, and 'Molly' is on everything else and what I use to introduce myself.
I just got out of grad school and my poor teachers would start each semester by calling roll call for my formal name, I respond, then not an hour later I will pull a teacher/ or student aside and introduce myself as molly, confusing everyone. I just graduated and half my program calls me michelle, the other half molly, depending on how long I was able to keep the names straight.
Applying for jobs is equally annoying, my resume states michelle but my email address has molly. My voicemail usually says molly but if i am applying for a job I switch it to Michelle and my friends start leaving me messages asking if this is still the right number.
These days its VERY hard to keep your business and personal life seperate. Think check writing, credit cards, and drivers licenses...not to mention introducing yourself when your nervous and accidently using the wrong name.
I LIKE the idea of keeping your name, I am all for it, but figure out the rules so you can be consistant and get into a good habit.

cant wait to wear my dress!
