Where do you purchase most of your casual clothing?
Most recently, I bought some shorts on Amazon. California gets hot in the summer, and I need some cooler clothes.
Do you get great deals on Amazon?
Sometimes, they have sales and bargains. Sizing can be a bit tricky. 
I bet buying online makes it difficult. Have you ever tried a clothing calculator? if so, how accurate are they?
I have never heard of a clothing calculator. How does that work? Does it help me save money somehow?
Shopfans has one. I am sure you can find more online. It helps save you time, it's a tool for online sizing.
That sounds helpful, especially since sizing can vary, depending on the company making the clothing. Some overseas clothing runs a bit small. I need to buy some summer footwear too.
You sound like you have figured out all the sizing tricks... lol
Not really. Shoe sizes can vary, but not so much as clothing. I'd like to find a comfy, yet stylish pair of sandals.
