For a polished office outfit, wear a fitted, opaque blouse or work top under your petite blazer. Choose a camisole or shell only if your workplace permits sleeveless tops; a plain T-shirt is a more casual choice for offices that allow it.
Choose a top that suits your office
The right layer depends on how formal your workplace is and how much coverage its dress code expects. Compare the options by coverage, formality and how smoothly they sit beneath your blazer.

| Layer | Best suited to | What to consider |
|---|---|---|
| Fitted blouse or work top | Most polished office outfits | Choose an opaque top that lies smoothly under the jacket. Petite styling guidance recommends a fitted top, and Petite.co.uk suggests pairing a petite blouse with a single-breasted blazer for work. |
| Camisole or shell | Workplaces that allow sleeveless tops | A camisole can create a lighter, more open neckline, but it is not appropriate for every office. Florida State University’s Career Center advises against camisoles and sheer blouses in its professional-dressing guidance. |
| Plain T-shirt | Casual offices or permitted casual-Friday outfits | It reads as less formal than a blouse. Petite.co.uk suggests a plain T-shirt under a lightweight work jacket for casual Friday. |
Three outfit formulas
Polished workday
Pair a petite blouse with a single-breasted petite blazer and tailored work trousers. This is the strongest default when you want a conventional office look.

Lighter layer, where permitted
Wear a camisole or shell under the blazer if sleeveless tops meet your office’s coverage expectations. If the dress code calls for more coverage, choose a blouse or another top with sleeves instead.

Casual office day
For a workplace that allows casual-Friday dressing, try a plain T-shirt under a lightweight blazer. Keep the top simple so the outfit still looks intentional.
Check the fit beneath the blazer
The inner top should lie smoothly rather than bunching under the jacket. Check that the shoulder area and sleeves feel comfortable when you move, and that the neckline and coverage are appropriate for your workplace. There is no universally correct neckline, sleeve length or fabric for every office or blazer.
