Welcome to Epic. Good advice from phil. Go to the ski shop nearest to where you ski (or at the mountain where you ski). Boots being the most improtant part need to fit your foot and lower leg correctly. You know if you have a narrow or wide foot, high or low arch, narrow or wide achilies/heel and long or short calf muscle. You need a boot that fits each of these areas properly. Also get one that is about your street shoe size, no bigger. They feel tighter when they are new and take a few days of skiing to pack the liner to where they don't feel too tight. The shop should also check your stance, so any adjustments can be made to allow for the inward curvature of your tibia/fibulia as you stand (known as the Q angle).
A modern ski should come about to your nose when standing on end (a general rule of thumb).
some skis are very heavy and can be skied a little shorter, while some skis are very light and can be skied a little longer.
The advantage of going to the shop either at or very near the resort where you ski most is that any additional fitting of the boots can be done while you are at the resort and many resorts have a demo center where you can try different skis and at some , boots as phil advised. There are women specific boots and skis, that is the best place to start.
If all else fails, go the the best graphics and colors that match your outfit.
Once you find what you want and the size that fits, remenber that the shops have sales up to 50% off by the second week in march (not a big help to you now).
Good luck, and have fun in your search.
