Yes and No. Linen is a lightweight and breathable material, making it great for keeping you cool in summer. Yet, suits with a high percentage of linen get easily stained and creased.
If you’re looking for a low maintenance suit for summer, linen may not be for you as you’ll be at the dry cleaners regularly.
It may be the material you’re looking for if you’d like to wear your suit casually but never to the office.
A suit made from lighter wool fabric is a better choice for summer as it’s breathable and can hold its shape throughout the day.
