I love your purchases! And I am pretty sure they will stand you in good stead come the fall. They have the femininity and pizzazz you typically look for in your wardrobe items and are in fresh, pretty colours.
I buy selectively during the NAS. I always replace/ upgrade my undies because the sale prices are excellent and those are really for all year. I also look at gear clothing if I need a gear refresh (that doesn't happen every year.) Again, that's for all year, so perhaps not relevant to your question.
My other most successful NAS purchases include footwear. I know my tastes and needs and it is rare for me to make a purchase in that category that doesn't work out.
I've also done well with bags at NAS. And with denim, which again, is a wear-all-year thing. And scarves. These typically become workhorse items.
Dresses and knits are trickier. Dresses because I sometimes get over-excited and forget my real needs. Knits because sometimes the quality turns out to be missing in the ones I buy. Having said that, I've also found some real winners in the sweaters department there.
I also have success with the odd big-ticket statement item. My Rag and Bone gilet falls into that category. I almost never wore it in Ontario but in a couple of months on the west coast I've already worn it more than it got worn in a couple of years back east. And whether I wear it or not, I love it. So there is that.
Examples of my most successful NAS purchases below. These are items that are still in my closet. There are others (mostly footwear and denim) that was equally successful but that I wore into the ground.
