Hi~
 

This is Teacher Rach~ Here are your corrections:

My husband doesn't wear a suit to work on weekdays except for Tuesday.

==> My husband doesn't wear a suit to work on weekdays except for Tuesdays.

Because he has meeting at company every Tuesday. ^^

==> Because he has a meeting at his company or workplace every Tuesday. ^^

• Great job~ Your errors are as follows:
• Add 's' at the end of a day if you mean every time that day comes.
• Articles: add 'a' before 'meeting' since it is a count noun and include 'his' before a noun to make it more specific.
• I hope the suggestions will help! Keep posting~~
