A Line Dress With Double Straps (Black)

pinafore, A-line dress, double straps, black
This is my first project here and was my first attempt in making a pinafore dress on my own; 100% hand-stitching and it took about 3 days. I made lots of mistakes while cutting and sewing; had to re-sew and re-open, again and again. :'( *embarrassed!*

It was supposed to be a very simple one; with a big bow at the back and simply plain at the front. But, after I had finished sewing everything, it felt a lil bit tight (AHH! :/).

So, I had no choices but to tweak some changes on this dress. I made a long cut medially on the front and put a 20" zip there. So, I took out the original shorter zip which I had sewn earlier on its left side.

Here came the problem; how to nicely cover this front zip? As I am simply a beginner in tailoring, I had no other ideas but to put a little bow at the end of this long zip. I might want to remove this little one later because I don't really like it. I have already sewn a big bow at the back, and now, another small one at the front? Do you think it's inappropriate and ugly? Do you have any other suggestions?

Please help! Thanks in advance!

P/S 1: I love those flowery buttons that I put on my double straps. It was taken from my old t-shirt that I wore on the first day while sewing this dress. HEHEHE. And, that 20" zip? It was taken from my sweater which I wore on the next day of sewing this stuff. HAHA! >:)
