alright if you want to know to dress.. dress like a male model. the whole thing with modeling is you have to STAND OUT FROM OTHER MODELS.. which the only way you can do that is with clothes.. Wear FLARE but keep it limited from one BIG article so you don't look too out there..
I rock either a bright orange shirt or i'll through on my gold shoes (i'm white) and a black and gold belt. The gold shoes are topic openers from girls, guys whoever.
For your hair cut suggestion. GO TO A GAY GUY.. girls will do what they think they'd like on you but a gay guy will do what they think will make YOU look good.
A tip for everyone who has shorter hair.. ASK your hair stylest to cut your blend from the short sides higher up on your head were it starts bending up to the top of your head. by doing this it brings out your cheek bones a lot better. Also if you can find out your heritage and then go and look and the hair style that best works with that.. i have a very european look and have a european style cut which is unique and stands out as well as goes well with my bone structure.
MY THOUGHTS ABOUT CLOTHING SIZE:
leave the baggy clothes for her to sleep in or you. dress in nice fitting shirts and pants with a good cut
American Eagle has a good cut and if you shop their sales rack good jeans can run 14 dollars. the issue with TJ max and all those is the quality isn't as good higher quality if your going to go for higher HB they pay attention to detail soo consider this or be cocky about how your clothes rock.
but if you don't have the best figure work on it go to the gym work out i'll be happy to help set anyone up with a workout but take care of yourself since you live with your body for the rest of your life. soo take care of yourself and pride in what you accomplish.
if you aren't to toned wear a fitted but not too tight shirt. but as you get more in shape (months to years) you'll get more compliments and can pull of more fitting shirts
Just my thoughts tho.
