Tim Gunn spent the episode visiting each of the designers at their individual homes to check in on their progress. First up was Kimberly Goldson in White Plains, MD, who is inspired by the pre-gentrified Brooklyn of her childhood. She wants her collection to "elevate" the Brooklyn girl in the way that she elevated herself. Tim thinks it's all very "her" but advises her to take some risks and wow the judges.
Next up for Tim is a trip to Maraval in Trinidad to visit Anya Ayoung-Chee, who has been inspired by scuba diving and the ocean. She's a bit nervous though because she's only got the fabrics sorted rather than any items made - and, as expected, Tim advises her to buckle down and start sewing.
It's back to New York for Tim to visit Viktor Luna who is working on an "urban coast" collection inspired by photographs he took in Mexico. Tim advises him not to overthink before making the trip to Queens to see Josh McKinley.
Josh is inspired by a variety of crazy-coloured fabrics and textiles but some of Tim's critiques include calling his choices gimmicky, verging on cheap and homely. Josh tells us that he ended up putting five or six prints to the side after talking with Tim and only has two finished pieces left.
It's soon time for everyone to gather for Fashion Week and they all get the chance to see each others' designs for the first time. Tim arrives to tell them they will each be presenting three looks to the judges but they won't be able to fit their models until right before the runway show.
At the runway, Heidi Klum explains that she and fellow judges Nina Garcia and Michael Kors will now view the three looks and decide who they want to see more from: "You are all very talented but unfortunately only three of you will compete at Fashion Week."

Heidi doesn't think Anya's bathing suit is very flattering and the kaftan colour is "sad". She also thinks that her evening gown looks like it was done in a day and doesn't flow well. Michael agrees, saying: "It looks tortured and satin shows everything." Heidi points out the gown should be the 'wow' piece at the end of the show. Michael and Nina don't think her styling is doing her any favours and say she should rethink some of the jewellery, belts and shoes to make the collection seem cooler.
Kimberly is up next and Michael says he loves the fact he immediately knows her clothes on the runway. He likes the way her collection is sexy despite the models being covered up, but thinks some of her styling is too heavy. Nina agrees that accessorizing is an issue, while Heidi doesn't like the bubble butt skirt because it reminds her of a cartoon.
Michael thinks two of Viktor's three looks are great, piling particular praise on his leather jacket, pants print and "impeccable" tailoring. Again, however, accessorizing is an issue - Michael says accessories should be used to complete a look not distract from it. He thinks the leather jacket should have been shown with simple black pants rather than a dress, suggesting maybe he turned the volume up too much.
Heidi thinks that Josh's designs are modern and forward with a good mix of colour. She loves his jacket but is not so keen on the seatbelt-style buckle on his jacket or the busy shoes. Michael loves his jacket and the back of his cocktail dress - but not the modesty tab at the front - but doesn't like the pantsuit/dress combination of his third look. He does, however, like the seatbelt buckle and when he suggests putting it on the cocktail dress instead of the jacket (where it initially was, according to Josh) even Heidi becomes a fan.
Josh and Viktor are the first to book their places at Fashion Week, leaving just Kimberly and Anya on the catwalk. Kimberly secures the third place but - there's a twist! Anya will also be showing.
