I personally think you may be at a good weight for your height, but it's usually your own opinion on things that matter.

I sometimes also think I would look better if I was a lower weight (I'm 5'4.5 at 110 lbs), but I can't stand not eating. So I focus more on exercising and training. If you like the lean skinny look, I recommend trying exercises like pilates, yoga or ballet. You can easily get a DVD and do stuff at home if you can't afford to take classes.

I personally love the Tracy Anderson Method because she combines all those types of lean muscular exercises. She also has a healthy eating plan if you want to change your diet. (I don't follow it because I like my food and it's hard to find some stuff here in Japan).
Here's a link to her site: http://tracyandersonmethod.com/
I find her method works if you at least stick to it. I'm trying to keep to it to prepare for my wedding in Hawaii later this year.

Also, something that may help, drink lots of water. If you think you feel hungry, drink a cup of water and see what happens after that. Sometimes when we think we are hungry, we are actually thirsty. So eliminate sodas, juices and alcohol. Switch to water and try to drink 2 liters or more of it a day. Your body just functions better that way.

I am at a good weight but I think I look better when I'm a bit thinner. Then my breasts look more in proportion and my waist looks smaller.
Congratulations on your wedding. Unfortunately I just started school so I probably won't be able to strictly stick to a healthy diet.
