After a complete debacle of dealing with poshmark sellers yesterday (who sent me an offer that I counter-offered and then they promptly declined it, deleted the listing, and relisted the item for $15 more than the original price), I abandoned my idea of getting some 2nd hand lulu stuff for my Cindy HM costume and discovered that a suitable tank (and matching leggings if it's going to be in the freaking 30s again!) on under armour's website that were delightfully discounted. I ended up ordering sparkle skirt fabric to sew my own because I could get 2 yards of each color shipped for less than the price or one already-sewn skirt.
I also purchased a UA shirt for my sorcerer mickey costume, and grabbed a headband on etsy from the same maker that I wore for my figment costume a few years ago; the figment horns were so light that I didn't notice that headband at all for the entire race. Hopefully she hasn't changed how she makes them and these work our as nicely.
And I'm just now remembering that my kids borrowed and then lost my good SPI belt that I usually bring. The one that has a water-resistant pouch for my phone and loops for my gels.
