I am absolutely horrible at doing my own nails. No matter what I do, no matter how careful I am, no matter what polish I use, I always seem to get clumpy nails that chip right away. I get so frustrated!!

However, my sister can do my nails using the exact same polish I've tried, and they'll last over a week without chipping!

Obviously, if I get a professional manicure, that will also last a while.

But, my sister can't do my nails every week and I can't afford regular manicures, so I need to figure this out for myself!

Any tips, polish recommendations, top coat recommendations? Help a girl out!
