i know most of you will say 21 for guys,

but im about 180cm now (6foot).

i'm taller than both my parents. (my dad by about 5cm).

when will i stop growing, or have i stopped already.

i am nearly 17, and about 60-65kg.

reason i ask is im getting a tailored suit,
and im wondering if i should allow the suit to be slightly bigger so that by the time i am fully grown,
i can still fit into the suit.

What do you need the suit for?

You can always have things taken in, its harder to let them out.

It's roughly 21 for males, around 18 for females. You're not supposed to get too much taller than your parents in theory, although diet/exersize etc. i'm sure would contribute to height. I am around 5 inches taller than both of my parents... and I think i'm still growing (i'm 18). What's this suit for? How expensive is it? If it's going to be really expensive and you're planning on using it more than once, use your common sence and get it slightly larger than you would do.

I stopped growing when I was like... 16. I was taller than everyone! and then all my friends reached my height.
I'm around 6'.
Ask your parents if they growed faster than their friends when they were young. We seem to stop growing quite young in my family.
I'm 19

fuck you guys, I started growing later than everyone else

mm
it's a tailored suit.

it will cost about $500 (pretty cheap for a tailored suit).

a tailored suit that is slightly to big for you...

no i've seen their work.
it's pretty good.

it costs more if you get extras though.

you missed the point brah.

a tailor cut suit is supposed to fit you perfectly, not fit for you to grow into.
