Shoes are super cute and fine for a regular work day, but NOT for your interview
Wish we could see the shirt, but we can't. A tank under it does make it sound too casual though. In general, a business shirt should be either silk (or silky fabric), cotton 'menswear-type' shirting (or similar fabric in a blend), or a light-to-medium weight silk-wool-like knit (NOT a T-shirt knit). There may be a few other options, but a T-shirt type knit is NOT what you want here, no matter what the cut or color.
Try cover-up makeup to hide it, then sheer hose. Opaque tights are not the right look.
You probably only need a day to clean and press, and should not generally need to dry-clean a suit after each wearing. Press or steam, maybe. Definitely have more than one top though as that will need to be cleaned.
Excellent! Just the right look and style, and a very reasonable price for the quality, comfort and versatility.
Can't tell from the photo, but they should 'skim' the tush, not hug, and your jacket should be in the same fabric and be long enough to cover the fullest part of your backside.
Looks to be since the color contrast is mild.
Your entire arm needs to be covered, sorry.
If you think finding a pair of comfortable heels is hard, try finding a super-professional pair of flats! Flats and near-flats have to be EXTRA professional to counter the 'little-girl' or casual vibe.
Suit looks fine, but NO t-shirts!
Honestly, that fabric says "fashion suit" not "interview suit". Wouldn't do it...
No bare skin -- Hose would be best, or sheer dark "trouser socks" in the same or darker shade as your slacks.
