My swimsuits are from Lands End. They are fabulous and amazing quality! For context, they survived 2 or 3 years in Las Vegas sun, and are still going strong! Not misshapen or anything. I highly recommend them! Worth the price, and usually on sale in Sept/Oct.
My pants: Sigh. I will find a pair of pants I love, and stick with them! My last pairs were from Costco and Sam's. Impossible to find now of course. And, since they are now officially threadbare, I had to buy new ones. After searching the local stores, including our 'outlet' stores, I ended up going to Amazon and finding a bunch in the "try before you buy". I found some Sketchers ones I like. Pockets! on yoga type pants. Seriously - pockets!! So, I went to Sketchers site. Not available. The irony! I ended up buying them from Amazon because of that.
My shirts/hoodies: They come from everywhere. I love a good hoodie for the fall and winter. I've bought hoodies and/or shirts from our library, Columbia Sportswear, Teepublic ('Scrapbooking is my superpower' along with other pithy statements), and Sam's Club. Old Navy too. I bought a few from Walmart, but the fabric was super thin, and stained really easily! So, no more. I've got a few from thrift stores too.
My skirts and dresses: Thrift stores. I've got some LulaRoe from Thrift Stores. Occasionally, I've gotten dresses or skirts from Burlington Coat Factory or T.J.Maxx. These are way easier to find at thrift shops in my size than shirts or pants.
