OOTD: Sweater Layering

My mom leaves today... such a bummer.
 
My spending habits should drastically improve with her gone!
It has brightened all of my days having her here... I am destined to go through some gloomy ones after she leaves!
 
How are you with sweaters?  I used to love big chunky sweaters, but my love for them has ceased a bit.  I like the warmth, but not the bulk.  I am a picky sweater connoisseur.  I don't like the knit to be to heavy or chunky or too 'cheap cotton' looking.
 
This gives you an idea of what I mean... two lovely sweaters of mine... this MK is such a beauty...
 
 
Recently I put on this lightweight GAP sweater... and was still cold.  The solution... add another layer!  It worked.  Two layers of thin sweater equals the same warmth as one big fat sweater, with no bulk!
