It will not be a big deal if you show some skin in hot climates. Aside from buying lightweight clothes with breathable fabrics, another way to keep the temperature down is by allowing the chest and neck to breathe. Here are some necklines that can be perfect for the summer:
There will be places and there will be days when we have to endure 100 degrees. Although the male physique will look good in tailored and fitted shirts, it can be a torture in hot climates. What will be more appropriate will be looser and clothes that allow air to flow thru them. If you are going for a beach holiday, these kinds of shirt will be idea.
If you will be going to the beach, you can go for tank layering. Put on a graphic tank top and a short-sleeve shirt. Pair them well with a pair of jeans to complete the easy look.
Knits are there any time of the year. There are knits suited for the summer weather. You can go for really thin ones made of cotton-silk combo. Of course a low-cut neckline is a must. It is more comfortable than a t-shirt and at the same time dressier. Wear this for dinners or summer night events.
Stay cool and enjoy the breeze with band-collared shirts. You will not have that collar on the back to deal with and all you have to do is undo some buttons for a very relaxed look. Complete the casual look by having some metals and leathers.
You can have up to three or four buttons undone when wearing a washed shirt. This look is not just for the suave men but anyone who is fit plus a dose of confidence can pull it off. Get summery fabrics for your shirt and pair it with your linen pants that look best with the low neckline. Trim your chest hair a bit for a cleaner look.
