Translation help

[sarpen]

I asked an acquaintance for helping translating the phrase "Let me see if my pattern will fit you." The sentence is spoken by a seamstress, so in this case "pattern" is referring to a pattern for making clothes. He suggested the following:

permitte mihi videre si exemplar mea erit apta tibi.

He also suggested I check here for a second opinion.

Any feedback you can provide is much appreciated.

Thanks!
