Your personal style should evolve. Getting dressed is at times also difficult for me and I do this for a living. I am always challenging myself in business in life and in what I wear.
Stick to what suits you, dress for your figure. I think it is so important to know your body type and become confident with your proportions. Always pay attention to the cuts and curves of your clothing and the little details.
Wear new combinations and learn to wear what you already have in your wardrobe differently. Especially if you travel for business. You do not need to pack many pieces, just pieces that you can mix and match and wear throughout the day or into the evening, with just a change of a shoe or a piece of jewelry or a handbag.
Your outfits are the same but because you are mixing and matching , they look different and fresh together.
