Bra size

Tamzyn

Not sure where to post this.. I moved to the UK recently from south Africa... in south Africa my bra size is a 34B... at Victoria secret I'm a 34D... their sizing is different... I bought 2 bras at Mark's and Spencer's and I bought them in a 34B the straps dont leave Mark's but around my chest area there is.. which means the bra is to tight.. but will the bra stretch? Cause at Victoria secret they said a bra shouldn't leave red marks on you
