This is what I call a detailed answer, thanks, let me add few words.
My first post sure made it look like the TV show has instantly changed my style, but I did say in another post that my usual style was classy just less formal than suits.
-True, most 18 year olds do not walk around in suits especially with ties and pocket squares, but do I really have to be like this part of "most 18 year olds". Interesting, but you have your point.
-Yes, I have never worn a suit on regular basis, yet whenever I had a chance to wear one it was awesome and made me even more confident (and that was before seeing the TV show.)
-Impress my family? Kind of why not, but I only said it would be nice to look good, my main point is to feel great when wearing a suit, and different than "most 18 year olds".
-I do understand the online shopping part and I totally agree on it. It's kind of stupid to spend $500 on my first suit (I work hard for that money) and just buy it without getting properly measured. I still remember when I was 8, and my parents were trying to find me good fitting suit, driving from shop to a shop, from city to city for the whole day without success. And true, I am an amateur and I do not really know what I am doing, that is why I ask. I liked the suit, I bought it, that's it.
-The travel is 14 hours long, UK > New York > Las Vegas.
True I am on fire after a suit and wearing one, partly because of a TV show. Please tell me, if it makes me feel great, it will somehow look good, because I want to, is there any major reason not to?
Interesting, really. I still do want to wear one, just because some people will think "oh he is too young for that" doesn't really bother me.
Really thank you for taking your time on answering, thoughtful.
