So I should get like a new outfit a week?
Dude im going to help you out.
First im not asking you to get your whole wardrobe changed overnight, but you need to change it entirely over time.
With that said and since you are on a budget, i suggest doing it slowly over time.
First thing, since you are starting new, get basic items. That mean nothing with graphics on them. Simple single color items, like T-shirts, long sleeve t-shirts, Henley, jeans, or chinos.
Make sure everything is fitted (i know you are short and so am i, but if you are in shape for your height, get slim fit or even more fitted, dunno your figure), and try to get more neutral colored items, like black, white, grey. If you are feeling adventurous, maybe through in some color here and there, but not loud colors like pink, green, etc.
My suggestions for basic items, go to Gap, Uniqlo, even Old navy. Even Kohls, they have decent brands for cheap.
If you want to pay more, go Banana republic.
Lastly, i suggest trying the clothing on in store, but buy online. Especially for Gap and Old navy, they always have a online store code for 30-40% off.
need more help, you can PM me.
