What are my options?
Mysuit MTM in NYC - Page 4
I've never heard of that before for an MTM place. If they had done their job correctly, there would be no need to get any alterations done. Since it didn't come out perfect (MTM often does not), it should be up to them to tweak it with some tailoring. This is why most MTM places include tailoring after the product arrives.
I would try going to the manager and asking what they can do to fix it. Do they offer any kind of guarantee?
