My suggestion is that you take her shopping with you and go try on lots of suits and let her pick or the one that she likes the best. If you seriously dislike her choice, you can say you prefer a previously tried suit. Hopefully you will enjoy the experience and come to some middle ground that you both can live with and you can truly be grateful and appreciative of the gift. If not, and it turns into a fight and resentment..., start looking to get out of the relationship while you can as it will only get worse. Sorry for the somewhat negative comment but in many ways I am serious. I wish I had looked harder for someone that I could get along with better. I have been married for more than 20 years and seem to argue with my wife about which way the wind is blowing.
