solid basic hoodie - but please don't sew the draw string in Fruit of the Loom!!
Size: XX-Large, Color: Black Pullover
I love these hoodies and actually have a few of them in my wardrobe - I would give them a 5-star as they're very comfortable, hold-up well to wear and tear, and they're pretty warm... They don't shrink or bleed dye in the wash, great stuff.
HOWEVER! They recently started sewing the drawstring in, which is really annoying... I wear the XXL size and the hood is still a bit small for my dome, so I typically don't need the drawstring, but now I can't remove it without trying to remove the stitching and damaging the hood or cutting the ends off, leaving most of them inside the hood - meaning you can't replace the drawstring should you want to (which sometimes I do, like if I'm skiing or what not)...
I also work with power tools, which make loose ends like drawstrings outright dangerous, so I really need to be able to remove them easily - I would give these hoodies a 5-star if they stopped sewing the drawstring in

Good value
Size: 10.5, Color: Black/Black
They fit and they stay on my feet (I was worried because these are slip-ons).

Comfortable lightweight sneakers for casual everyday wear
Size: 9.5, Color: Navy
These sneakers feel like a decent value for the price. They are very lightweight, which makes them comfortable and easy to wear throughout the day, though that also means they feel a bit less substantial than more supportive athletic shoes.
I have mainly been using them with business casual office outfits, and they work perfectly well for that kind of light-duty everyday wear. I would not personally use them for anything especially active since they do not offer a ton of support, but for casual use they have been great. I also like how easy they are to slip on and off. I typically wear a size 9.5, and these fit true to size for me.
