[separate post coming on what I pack in my travel purse...]
Travel size toiletries (up to 3 oz.)
GALS: all of those Sephora samples you get in your package? perfect time to try them out!
Pro-tip: Remember that Sephora gives out free samples. When I was in Portland a few weeks back, I forgot to pack my BB cream, so I went to the closest Sephora and got a sample size of it. woot woot
Makeup wipes. By the end of the day, you're exhausted from site-seeing and travel festivities. Make it easy on yourself and just use a wipe to take your face off.
Individually sealed packs of Advil and/or Pepto because, new environments and food. Nice to keep one in your purse at all times.
Chargers + USB male to female extension. Reason being: you don't know where the outlets are going to be, so it's nice to have an extension on hand!
Neosporin + band-aids [if I'm traveling in a bigger group, I'm likely to bring a small band-aid pack.]
Shoe bags. The ones I own are below, but there are a ton of options on Amazon. I personally like these ones because the different colours help me remember which shoes are in which instead of looking through them.
Packing cubes. The ones I have are below as well (2 medium, 2 large cubes). To be fair, I haven't actually tried them out yet! I got them on sale on Prime Day and am really excited to try them out. I shall review them once I use them.
