Tutorial Notes: Thank you for being so patient and understanding with my schedule, SaveYou!!

That was good! Grammatically I only noticed that you used the word "to" instead of "too" when you posted the following: so she'd assumed she could wear it to
The word "to" is typically used when it's describing a verb in motion and "too" is used when you're wanting to say "as well" or expressing an excessive amount of something, such as "too much" or "too soon."
Grammar aside, I found that I had to read the following twice to put into context the legal drinking age: She was underage, by a year, but she never actually drank any alcohol.
The legal drinking age in America is 21, the legal drinking age in probably the rest of the world is 18. I'm guessing we're outside of America on that one but I'm not completely sure. This wasn't a bad thing, it was just from my perspective it took me a second to put that into context.
As far as character development goes, sometimes less is more. This is entirely up to your style of RPing, but to pull the reader's attention in, sometimes you have to slowly reveal information about your character as you continue posting. Make it more suspenseful, you know? Get the readers to ask questions that keep them hooked to reading so that they can answer those questions. For instance, when your character entered the bar, you could have just stopped her description at her age so the readers would have to guess what she was doing there. And then from there slowly give hints as to why she was there.
Another thing I noticed was that you were very good at describing what your character was doing and what your character looked like, but I wish I could've known what was going on in your character's head and what she was feeling at the time. Get the readers to feel what your character is feeling, try and describe that feeling and channel it to your readers.
I also wish I could have seen a little bit more of the environment encompassing your character, basically describe the setting. This almost always helps to set the tone and the mood of the RP.
I actually have to go to work right now x.x but I will make a followup post as soon as I can! Would you be interested in doing a group tutorial session where I would mediate you and others as well under one topic? I would make sure that if you were interested, that you would be grouped with people on or around your level. Let me know when you can! And again thank you so much for being patient with me!! <3
