New uniform - feel horrible

[Cocoooo1]

I’ve been offered a new job and I got my uniform today. I feel like it’s very unflattering on me on my hips and arms and I feel insecure. Has anyone got any tips on how to make me feel better in the uniform?

If it’s not sized correctly can you ask for bigger/smaller sizes?

Can you buy a different size? Work uniforms are made from cheap materials usually so sizing up will help it feel better

Get a larger size and get it altered to fit better

Have you been given the correct size?
Are all parts completely compulsory or can you wear - for example - any smart black trousers rather than the ones they provide.

If its the correct size, it probably looks similar on everyone. Can you add a cardigan or jacket?
