Čelar was born in Pančevo, Serbia. After completing high school, she continued her education in the fields of business economics,
e-business, and internet marketing. In the mid-1990s, at the invitation of professionals from the fashion industry, she moved to Milan, where she began her international career in the world of fashion.

During nearly two decades of living and working in Italy, she gained extensive experience as a model, scout, producer, and organizer of fashion events, collaborating with numerous renowned brands and fashion houses such as Ermanno Scervino, Krizia, Donna Karan, Calvin Klein, and many others.

Her professional path began at the agency Fashion Model Management, where she progressed from model to scout and client relations associate. Through her work and travels across South America, Africa, Asia, and Europe — where she is now based — she established strong professional connections and successful collaborations worldwide.

As her career in the fashion industry continued to develop, she applied her knowledge and experience to various projects and event organizations, including those she carried out for the company Mondialpelli, as well as numerous activities related to the fashion house Gianfranco Ferré. During this period, she recognized the importance of international cooperation and markets, and accepted a new professional challenge by joining the main organizing team of the largest bridal fashion fair, Tutto Sposi, in Naples.

She further developed her competencies by creating clear strategies for positioning and developing brands beyond the local level and placing them in a global context. This expertise and experience led her to the position of Marketing Director at Yes London, a role she held for several years.

Thanks to her responsible approach and expertise in campaign development, production, advertising materials, brand communication, press content, and brand standards, she successfully contributed to increasing the global recognition of the Yes London brand, achieving significant results and opening new markets.

In 2011, she founded the agency Alek K Fashion Event & Photo Production — a concept that brings together the knowledge and competencies she acquired throughout her professional career.

Today, after years of successful operation, the agency continues to function as a stable and recognizable production and educational platform within the fashion and event industry across the Adriatic region.

Within the agency’s activities, she has built strong trust and a solid reputation among numerous clients, structuring the agency’s work through three main directions in which it confidently operates on the market.

The first area focuses on the organization and production of fashion shows, campaigns, photo and video productions, online activities, as well as numerous corporate events where the agency acts as a reliable partner and support. Within this segment, she has assembled a large and highly specialized team capable of providing full support in the realization of fashion events or event concepts, from development through to execution.

The second important segment of the agency’s activities is international cooperation. Through this direction, the agency actively participates in promoting new faces in the modeling industry worldwide, collaborating with numerous modeling agencies across the globe.

An important additional focus is the international promotion of brands and fashion labels through partnerships, creating bridges and opening opportunities for designers and fashion houses to gain international recognition. This includes cooperation with the international project A-Coded World in 2016, through which numerous presentations of foreign designers were organized during Milan Fashion Week. Similar presentations have also been successfully carried out in European, Russian, and Middle Eastern markets.

The third segment reflects the most current and responsible approach to business. In 2020, she launched the project Be a Model by Alek K, which combines education, mentorship, professional production, social responsibility, and sustainability.

Through the Be a Model project and its workshops, more than 1,000 participants have taken part so far, with the support of numerous partners who recognized its significance beyond the fashion industry. The project places Aleksandra’s vision within a broader framework of social responsibility, through which many successful initiatives and activations have been achieved.

Through Be a Model by Alek K, Aleksandra has drawn on her decades of knowledge, competencies, and experience working with young people, shaping the project as a form of education and training that offers far more than a fashion concept. It emphasizes both personal and educational development in the lives of younger generations, who are the primary focus of the project.

The broader potential of the project has been recognized, and it is currently being further developed with the aim of reaching an even wider target audience.

Aleksandra lives and works between Belgrade and Milan. She is married and the mother of a son, Ogi.

rođena je u Pančevu, Srbija. Nakon završene srednje škole obrazovanje nastavlja u oblasti poslovne ekonomije, e-biznisa i internet marketinga. Sredinom devedesetih, na poziv ljudi iz modne industrije, seli se u Milano gde započinje međunarodnu karijeru u svetu mode.

Tokom skoro dve decenije života i rada u Italiji ostvarila je bogato iskustvo kao model, scout, producent i organizator modnih događaja, sarađujući sa brojnim renomiranim brendovima i modnim kućama poput Ermanno Scervino, Krizia, Donna Karan, Calvin Klein i mnoge druge.

Profesionalni put započela je u agenciji Fashion Model Management, gde je od modela napredovala do scouta i saradnika zaduženog za odnose sa klijentima. Ostvarila je čvrste poslovne kontakte i uspešnu saradnju putujući i radeći, od Južne Amerike, preko Afrike, do Azije i Evrope, gde joj je danas prebivalište.

U nastavku karijere u svetu mode, svoja stečena znanja i iskustva upotrebiće i na projektima i organizaciji događaja poput onih koje je realizovala za kompaniju Mondialpelli, kao i brojnim aktivnostima vezanim za modnu kuću Gianfranco Ferré. U tom periodu shvata značaj međunarodne saradnje i tržišta, i kao novi profesionalni izazov prihvata da bude deo glavnog organizacionog tima najvećeg sajma venčanica Tutto Sposi u Napulju.

Svoje kompetencije razvijaće stvarajući jasne strategije u pozicioniranju i razvoju brendova koji prevazilaze lokalni nivo i postavljajući ih u globalni kontekst. Ta kompetencija i iskustvo dovode je u poziciju direktora marketinga kuće Yes London, koju će obavljati nekoliko godina. Zahvaljujući svom odgovornom pristupu i znanjima u realizaciji kampanja, produkciji, reklamnim materijalima i aktivnostima, press sadržajima i komunikacijama, kao i definisanju standarda brenda, uspešno će raditi na podizanju prepoznatljivosti brenda Yes London na globalnom tržištu, gde ostvaruje značajne uspehe i otvara nova tržišta.

2011. godine osniva agenciju Alek K Fashion Event & Photo Production, kao koncept koji objedinjuje stečena znanja i kompetencije koje je sticala kroz svoje profesionalno iskustvo. Danas, nakon godina poslovanja, agencija kontinuirano i uspešno posluje kao stabilna i prepoznatljiva produkcijska, ali i edukacijska platforma u oblasti modne i event industrije u Adria regionu.

2012.
U okviru aktivnosti agencije, svoju reputaciju i poverenje brojnih klijenata sa kojima sarađuje deli u tri pravca kojima suvereno vlada na tržištu delovanja.

– Prvi deo usmeren je na organizacije i realizacije modnih revija, kampanja, foto i video produkcije, online aktivnosti, kao i brojnih korporativnih događaja u kojima učestvuje kao relevantan partner i podrška. U okviru ovog pravca oformila je veliki i usko stručan tim koji može da pruži kompletnu i kompaktnu podršku u realizaciji celog modnog događaja ili event koncepta i njegovu egzekuciju.

– U drugom delu značajnih aktivnosti agencije je i međunarodna saradnja u okviru koje aktivno učestvuje u promociji novih lica u svetu modelinga worldwide, sarađujući sa brojnim modnim agencijama u svetu. Pored toga, kao značajnu međunarodnu aktivnost u fokus aktivnosti svoje agencije stavlja i promociju brendova i modnih marki kroz partnere sa kojima radi, stvarajući mostove i otvarajući mogućnosti međunarodne prepoznatljivosti dizajnera i modnih kuća – ne samo u okviru saradnje koju je potpisala sa međunarodnim projektom Acoded World 2016. godine, sa kojim je ostvarila brojne prezentacije kolekcija stranih dizajnera tokom milanske nedelje mode, već i šire. Uspešno je realizovala takve prezentacije i na evropskim, ruskim i bliskoistočnim tržištima.

– U trećem delu svojih aktivnosti, vodeći se najaktuelnijim i najsavremenijim pristupom odgovornih kompanija, pokreće 2020. godine projekat Be a Model by Alek K, koji predstavlja spoj edukacije, mentorstva, profesionalne produkcije, socijalne odgovornosti i održivosti.

Kroz projekat Be a Model i radionice koje se realizuju, do sada je prošlo više od 1000 polaznika, uz podršku brojnih partnera koji su u njemu prepoznali značaj u kontekstu koji prevazilazi modu, već Aleksandrinu ideju stavlja u okvir društvene odgovornosti – na koji način su do sada ostvareni mnogi uspešni koraci i aktivacije.

Kroz projekat Be a Model by Alek K, Aleksandra je na najbolji način uključila svoje višedecenijsko znanje i kompetenciju, svoje sposobnosti i iskustva kroz rad sa mladima, i na najbolji način zaokružila ovaj projekat kao vid obuke i sticanja znanja, koje pruža mnogo više od modnog koncepta – već naglašava didaktički, ali i lični razvoj u kontekstu života najmlađih generacija kojima se projekat posebno bavi.

Kroz ovaj projekat prepoznat je i širi kontekst na kome se trenutno radi u cilju da postane namenjen još široj ciljnoj grupi.

Aleksandra živi i radi na relaciji Beograd–Milano, udata je i majka sina Ognjena.
