I tend to be all over the map. Sometimes I go for a few months without buying anything and other times I buy several items in a week. There is no particular pattern. I just depends upon seeing something that I like. However, my closet is to the point where some lesser items need to go in order to make room.
Unfortunately with the coronavirus I haven’t been able to go to my favorite thrift stores here in town. On the other hand, there have been major sales with departments stores and other shops. As an example, I bought a pair of BORN sandals for $28.50 that normally sell for around $100 (wearing them right now, as a matter of fact). I’ve also bought some knit shells from Blair for $5.
Have fun and shop wisely!
