BOOTS!
Gear! I love purchasing outdoor clothing and workout gear-- especially running shoes!
Socks, undies, and bras (have to control myself when not in need, but I do enjoy the process of the renewal and how replacing a whole class of clothes feels).
PJs and loungewear--- this is one of my favorite things to browse for, although I like to get stuff on sale, spending money on "myself" with no way to justify it because of a "public" need feels so decadent (I grew up in a house where my parents each had one pair of short elastic waist sweatpants that they wore for lounging every evening-- 1 pair).
Long sleeves tees make me insanely happy-- if I could find a simple pullover sweater I liked I have a feeling that those would be the same.
Hats! Oh I love hats. Right now my list has another ball cap, a fedora, and a panama on it.
Yardley soaps-- one of the few fragrances I like (both the lavender and rosemary and the almond) and things that smell like shea butter.
Nice tea, coffee, or chocolate.
