Graduation Ball Dress Dilemmas

Readers, I need your help. What on Earth am I going to wear to the Graduation Ball? It's on the 1st of June, so I've got time (I haven't even bought my ticket yet eek!), but I'd feel a lot better if I just had an inkling of what I could wear. I've scoured all the affordable online websites (H&M is a bit shoddy, isn't it?) and haven't really found anything. Although, if the weather was perfectly sunny as it should be at a graduation ball, I'm thinking this dress could potentially be a winner....

Miss Selfridge £75

....because it's very Erdem SS11 and it covers the arms (bonus), accentuates the boobs (bonus), and hides the random 'stress rash' I am suffering from, which the doctor said might not go for another eight weeks (definite bonus)! I'm going into Manchester tomorrow to see if there's anything ball-worthy, so hopefully Miss Selfridge will have this in to try. I don't want to go down the full on, ballgown route, but I also don't think I fancy something short either (unless it's the cream French Connection Sasha dress, which I've been lusting after forever). 

So, if you think you've seen something you imagine to be 'Miss Dolly-like', please let me know because if this dress doesn't look right, I'll be panicking!

In other dress dilemmas, I'm still debating what to wear to Paris, but I'm liking this midi dress from Topshop, which I'll be able to accessorise pretty easily...

Isn't it so much better now that you can see what the clothes look like on at Topshop.com?

As always, let me know what you think!
