The top part fits a little loose. Though I would imagine it's quite difficult to find nice suits designed for women and in women's sizes. Especially at an affordable price. :'( You still look great though!!!!!! More on reddit.com

The pinstripe suit is deeply associated with the business world, and with finance and banking in particular. It is said that the stripes in the suit echo the ruled lines in a ledger page. Pinstripe and (more defined) chalk stripe suits are also associated with the mobsters of the 1920s and 1930s . As such, the look can have reverberations of money, power, and sometimes greed or shadiness . When worn outside of business contexts some degree of "I don't care" may be required to achieve the look; and the payoff is a projected image of power that some will respond to very positively. Pinstripes may be seen as part of the alpha male arsenal. Double-breasted, the look will carry even more sartorial weight. The addition of flourishes like bright silky tie, pocket square, cufflinks, colorful socks, power shirt, or flower for the lapel can thrust the monied and sometimes dark implications of the pinstripe suit into a more elegant arena . Here's Ryan Gosling wearing it. Ten years ago or so, the pinstripe 'blazer' came into fashion, especially dressed down and worn with jeans. It's a slick look best worn by those under 30 years of age (though others with a youthful air could make it work). Strictly speaking, there is no such thing as a pinstripe blazer; one would instead call it a sportcoat or odd jacket. Pinstripes are more typically reserved for a full matching suit, so wearing the pattern in an odd jacket may raise a few eyebrows, as it could seem that parts of a matched set are missing. And this, of course, is what the stylists intended — to mix it up and bring a perhaps business-associated pattern into a more vibrant usage. The 'pinstripe jacket and jeans' look is a bit overplayed by now. But I believe it will still have a strong following for some time. Younger folk, who maybe haven't had as much exposure to the complete pinstripe suit in its business context, may continue to accept the odd pinstripe jacket with jeans as a more powerful and stylish take on the standard blazer. Fashion's embrace of and subsequent reaction against stodgy traditions has produced many interesting takes on the striped suit, including its adoption into the rock and mod vocabularies , especially (but not exclusively) in Britain. Pinstripes have more play in general in the UK, and may be commonly seen in a wider range of looks there than in any other country. More on reddit.com

There isn’t any rules against it but it’s pretty hard/tricky to do. More on reddit.com

From the looks of it both the shirt you're wearing and the jacket are waaayyy too tight. I know you said you're bending over (?) in the photo but you'll be sitting in an interview so probably the same effect. I would get a new jacket if you can (I'm also not feeling the pinstripe...) and would go for a white button down underneath - always your safest bet, especially if you're interviewing somewhere corporate America-ish.

If you can't, try to pick something else as professional as you can (post pics?). I don't know if it feels comfortable but if you aren't comfortable in the interview (as comfy as you can be in a suit) you probably would be better off looking more casual anyway.

Edit: typo and good luck!!
