I'll post here what I just posted about Jourdan Dunn in another thread when I met her:
I remember a few months ago I was walking out of the building and there was a chick walking in front of me with some really cool sneakers, so I said "Hey, nice kicks" and when she turned around, it was Jourdan Dunn! She said "Oh, thank you." I was like "Oh, hi Jourdan" and she replied "Hey, how are you?" Me: "I'm doing great, thanks. Yourself?" Jourdan: "I'm fine, thank youuu." with a big smile. All this happened while we were walking. Then she got into a cab and waved good bye
Another highlight was meeting Joan Smalls for the first time. She was coming out of a party in West Village one night and there were a ton of photographers/paps screaming her name and trying to get pics. It was really scary because she was trying to get away and they had surrounded her and you could hear her saying "No, no..." Anyway, I happened to be standing near the SUV she was getting in and I said "Hi Joan" without really thinking anything of it, but she came up to me and said "Hello, I'm Joan" I said, "Hi, I'm a really big fan of yours" and she responded "really? Thank you! I'm honored to meet you"... she actually used the word "honored" and I'm just thinking, OMG, to meet ME???... Anyway, after that little exchange I wanted to ask for a pic but was kinda embarrassed, so I was fidgeting with my phone

She got the hint though because she said she's a bit sweaty from being inside but she'll take a pic with me. We took a couple pics and she got into the SUV. Her Bf came out of the party as well and then, next thing I know, Riccardo Tisci walks out and goes to talk to Joan before they all left.
Next awesome meeting was Karlie Kloss. I had to go to my office on a Saturday morning and was not very amused about it. I walked into the lobby and saw this really tall chick walking ahead of me towards the elevator bank. When I got there, it was Karlie Kloss!! I said "Hey Karlie" and she replied "Hi, how are you... wait, you're going to work on a Saturday?" I found how relaxed and easy to talk to really amusing. Somehow we got into talking about her learning to code and she told me how much she's really enjoying it. Unfortunately the elevator car arrived and we were taking different elevators so she had to go but she wished me an amazing weekend and told me not to work too hard

I tweeted her that afternoon and she favorited it.
Major Disappointment meeting was Daria Strokous. I was at the standard hotel one evening having drinks with friends and didn't realize that the CFDA after party was going to be there. As the models and celebs were arriving people were going crazy! Anyway, I remember some of the models arriving and because they aren't known, they kinda just walked through, except a couple who had a few fans and would stop to say hello or at least smile. It was pandemonium when Karlie arrived and shortly after Daria S arrived. I guess nobody knew her because they weren't taking pics or anything, but I actually like her as a model so when she stopped in front of me, I said "Oh hi Daria." Homegirl just glared at me, turned around and walked off. My friends who were there were like "whoa! what crawled into her panties?!"

... Anyway it was fine because Alessandra Ambrosio arrived and took a couple pics with me (Total sweetheart!) as well as Lily Aldridge. When Joan arrived though, I wanted to take pics but it was TOTAL chaos and I was being knocked left and right so I walked off to a safe place.
Met quite a few others that we mostly really sweet. Off the top of my head, Daphne G was nice. I met her out at Troy one night. Senait in my work building as well as Grace Mahary. Binx was very funny. Among the guys, River is cool, Corey Baptiste, Andreas Lindquist, Garrett Neff, Corey Bond, Sean O, Steven Chevrin, Nikola J and a few others. Mainly pleasant and receptive.
Among Designers, I've met many but Prabal Gurung and Riccardo Tisci remain the most memorable experiences, mainly because they were just so incredibly nice and talkative. Prabal even remembered me one night I was out in West Village and he came up to say hello. I'm like a nobody! He's a sweetheart
I forgot to add that Peter Dandas was really nice as well. We took a couple selfies and then he was like "Ok, now let's take a funny one and stuck his tongue out."
