Anyone out there do martial arts?

[large_lump]

Hi all. I started martial arts last week and loved it so am signing up! But I have a massive fear that im too fat to fit in the uniform! This might sound silly but I'm so scared about it as I'm a size 20 ish and the uniforms sizings don't make any sense to me!

Can anyone reassure me or explain to me how it works please?! I'm dieting and exercising so obviously don't plan on being this fat forever but I can't lose 7 stone by Wednesday! Lol

Thanks
