If you can't love her in a jilbab/hijab/niqab, you can't truly love her in anything else either. She will be most beautiful to you when she is obeying her Lord. She will be the most beautiful when she is trying to make her way to Jannah. And if you can't see the beauty in that, then your perspective of beauty is distorted. If you can't love her enough to help her attain Jannah, then perhaps you don't love her at all!
