Frequently Asked Questions (FAQs)
1. Which shirt fabric is best for summer?
Linen is the best shirt fabric for summer because it is breathable, lightweight and dries quickly. Light cotton is also a comfortable option for warm days.
2. What is an overshirt?
An overshirt is a slightly heavier shirt designed to be worn open over a t-shirt or polo, like a light jacket. It adds a layer without the bulk of outerwear.
3. How should a casual shirt fit?
The shoulder seam should sit at the edge of your shoulder, you should be able to button it comfortably, and the hem should fall around mid-hip if you plan to wear it untucked.
4. What is a mandarin collar shirt?
A mandarin collar shirt has a short, stand-up collar with no folded points. It looks clean and modern and works well buttoned to the top.
