Hi Purple Unicorn, I think your FI looks fine, but comfort is number one because you are both going to be excited, nervous, etc on the big day. Another thing I'd suggest taking into consideration is the destination. If it's hot and humid, I'd go with loose fitting! What I did for my FI (or now husband!) was went out and bought a second pair of the same pants one size bigger and made him try those on. As soon as he tried on the bigger pair he made up his own mind and I returned the smaller pair. At the end of the day, it's his decision and how he feels is most important Ginger - Blue Petal Weddings
