Someone got me a twin tipped polo from Fred Perry in size M. The chest and waist feel a little to large so I went to the store to see if S would fit better. Turns out S is a little too tight in the chest and the arms/shoulders are just too tight. The arm opening is just too small and my upper arms feel constricted. Are the jump in sizes this big for all FP ranges?

The store personnel told me that all polos are slim fit now, even thought there are no labels.

I kept the M in the end. Hope it will shrink a little after a wash

Thanks. It worked. I used equal parts room temperature water and boiling water. Didn't want to use boiling water on it as I was afraid the colour may come off.
