Husband over possessive?

I was a person who was always considered ugly because of my weight issues all my life. I was teased and mocked at. So I was always one of those who was not considered nearly beautiful even though I have a beautiful face and heart! So now fast forward to 2011! I am happily married and have 1 baby girl who is 1.5 years old now. I recently lost like 55 pounds and look good with a lot slimmer body! Yup I worked my *** off for close to 12 months to get where I am now. Now I suddenly am overwhelmed by all the external attention and feel more confident. The problem is I might have turned into a little attention seeking woman!! lol I dont dress like a sl** but I do wear clothes that are SLIGHTLY revealing and a little tight. But my husband has suddenly started demeaning me for looking a little sexy! for a change!! .... I am never ever going to cheat on him, nor do I ever give any leads to other guys who tend to notice me!!! Am I wrong! Should I stop dressing the way I am dressing now for my husband?? please any opinions!
