Since I know now - thanks to your email - that I didn't overstep my bounds last time with my review, I thought I'd leave another for this chapter.
There are two main things I look for in writing (aside from the plot itself, of course). These are sight and sound - can I find myself drawn into the world or not? In other words, description to see what is going on and dialog to hear it.
Your dialog in quite good. The only thing I'll mention about it is the use of string capitals (MA-THERR, MY, ONLY, etc...) It is often a good idea to avoid using these at all - good dialog gets the volume and emotion across without visual queues to help. Your dialog has the strength to it, so it doesn't really need the strings.
As for description... it's not bad, but it could be much better. There are four basic types of description - people, places (which includes objects), events, and beats. Depending on the character whose POV we are using (I assume Kat's in this case), we will see different things. Is Kat a person who sees people first, or things first? I can't tell by this point because neither are highlighted much at all. Take the dress for example. I wasn't sure what was wrong with it for quite some time - yes, there was a stain on it, but what colour was the dress originally? And where is the stain? And just what is Kat wearing while she is holding the dress out for her mother to inspect? Eventually, it comes across that the dress was red, but that's about all I got out of it. To really bring her to life - to see and hear her - you need to establish what kind of observer she is in the little scenes like this one.
.
That said, I loved the ending line without question - The party was going to be such a disaster, I could just sense it. That line says so much about Kat, and was excellent.
.
I do like this piece. After rereading my review, I thought it prudent to mention that again - this seems a little harder than usual, after all. But I do like it, and I look forward to seeing more, too.
Incidentally, I looked at your profile. Congrats on getting published! I just wanted to mention, though, that things put up here have official copywrite on them anyway - I'm intending on publishing the piece I put up once it's done, but I'm using this site as testing grounds to get the kinks out of it first.
Take care.

Your comment couldn't be more welcome. and don't tone it down in the future! this sort of stuff really helps. Its SORT of a prologue... i kept it short at first, knowing the 5 second attention span of most readers here. There will be much more to come though. Thank you,

I'm not sure what to say about this piece at this stage - there's not much here to comment on. However, the diary entry was interesting enough to make me leave some sort of comment.
This seems like a prologue of some sort, but it doesn't quite give enough information to let us grasp at straws - the suspense and mystery is too weak because there isn't enough given.
I'd like to know a bit more about Katerina, personally. What does she look like, how old is she, where is she from, etc...

Sorry if this sounds like a harsh critique - I am trying to help. I'll tone it down in the future if you wish.
