HELP! Graduation Advice, Please :)

The countdown now reads: 44 days left until graduation!

On May 17th, I will walk in both my university and department graduation ceremonies. I am so excited, it's unreal. I am in the midst of creating announcements and I will be sure to share them here! However, I need some help with some other decisions I need to make! Hopefully y'all can help me!
1. To decorate or not to decorate? I have seen the cutest graduation caps on other blogs & pinterest. I can't decide if I want to decorate mine or not! Right now I'm leaning towards yes, decorate...any advice? What sort of paint/pen should I use? If I print out something, how do you attach it to your cap?? I was thinking of putting my monogram & maybe some message? Maybe a bow? Maybe an apple to represent me being a future teacher? I have no idea!
2. What to wear!? I know I am going to wear a dress, but I am stumped on what dress to wear. My gown is black. I have a strapless, white eyelet dress OR a Lilly dress OR another solid color dress. This may require it's own post later on! Right now I'm leaning towards Lilly. Advice??
3. Flat sandals or wedges? This is another tough decision. I'll most likely be doing lots of walking, so I can't decide if I want to be comfy in sandals (Jacks) or be a little more dressy/cute/tall in wedges? What do y'all think?
4. Did you carry something with you? I'm thinking that I'll want my phone with me, maybe some chapstick or something...did y'all carry a clutch or anything with you? Or did your outfit have pockets? I guess this will be something to consider when choosing my dress!
5. Miscellaneous Anything that you wish you had with you/hadn't done/had done?? Did I miss something I need to think about? I am up for any and all advice!

Thanks, friends! I appreciate your help!   Happy Wednesday!
