Q,Q,Q,Q,Question!

These are the question I have recently.

1) Differences between Samantha Thavasa and Samantha Vega - as for me, it seems like same bag company. -

2) This is a question my friend asked me, "Why Louis Vuitton can be pronounced in that way?"

3) Finally, can you recconmend a cake shop for a christmas cake?

If you can give me answer to any of these questions, please let me know. Thank you.
